39. The Rate constant of a reaction doubles with a _______ rise in temperature.

A. 10 degrees

B. 40 degrees

C. 30 degrees

D. 20 degrees

Solutions

The correct answer is 10 degrees.

The Rate constant of a reaction doubles with a 10 degrees rise in temperature.

Key Points

The rate constant is defined as the proportionality constant which explains the relationship between the molar concentration of reactants and the rate of a chemical reaction.
As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10°C rises in temperature.
This is due to an increase in the number of particles that have the minimum energy required.

Additional Information

The rate constant is denoted by ‘K‘.
The reaction rate constant depends on temperature.
Increasing the temperature of a reaction generally speeds up the process (increases the rate) because the rate constant increases according to the Arrhenius Equation.
As T increases, the value of the exponential part of the equation becomes less negative thus increasing the value of k.
(Increasing the temperature increases the rate constant.) If the temperature is lowered then T₂ < T₁ and the right side of the equation is negative. Thus k₂ < k₁. (Decreasing the temperature decreases the rate constant.)

A. 54,840

B. 58,400

C. 54,280

D. 54,080

Solutions

Given:

Present population of a town = 50000

Increasing rate of the population per year = 4%

Calculation:

Population of the town at the end of one year = 50000 + 50000 × 4/100 = 52000

Population of the town at the end of two years = 52000 + 52000 × 4/100 = 54080

∴ The required population = 54080

Alternate Method Effective rate of increase in population: a + a + a × a/100

⇒ 4 + 4 + 4 × 4/100 = 8.16%

Total population after 2 years = 50000 × (100% + 8.16%)

46. Amar Jeet Singh can complete a piece of work in 5 days. With the help of his son he can complete it in 3 days. In how many days can the son independently complete the work?

Solutions

Given:

Time taken by Amar Jeet Singh to do the work = 5 days

Time taken by Amar Jeet Singh and his son to do the work = 3 days

Formula used:

Total work = Efficiency × Time

Calculation:

By LCM Method

Let the total work be the LCM of 5 and 3 as being the common multiple.

Efficiency of the son = 5 – 3 = 2 units per day

∴ No of days taken by the son to do the job = 15/2 = 7.5 or days.

Alternate MethodLet the total work be = 1

One day work done by Amar Jeet Singh = 1/5

One day work done by Amar Jeet Singh and his son = 1/3

⇒ One day work done by the son = 1/3 – 1/5

⇒ (5 – 3)/15

⇒ 2/15

∴ Time taken by the son to do the job = 1÷ 2/15

⇒ 15/2 = 7.5 days

48. Five bells commence tolling together and toll at intervals of 2, 4, 6, 8, 10 seconds respectively. In 30 minutes, how many times do they toll together?

A. 16

B. 15

C. 14

D. 18

Solutions

Given:

Six bells start tolling together and toll at intervals of 2, 4, 6, 8 10 seconds respectively.

Concept:

LCM = Least Common Multiple

Calculation:

LCM can be found out by prime factorization

2 = 1 × 2

4 = 22

6 = 2 × 3

8 = 23

10 = 2 × 5

LCM (2, 4, 6, 8, 10) = 23 × 3 × 5 = 120

Bells toll together after every 120 seconds.

Number of tolling the bells in 30 minutes = (30 minutes × 60 seconds)/120

⇒ 1800 seconds/ 120 = 15

∴ Total number of times of the tolling of bells after they toll for the first time

⇒ 15 + 1 = 16

Mistake Points If two bells after 2 seconds and 5 seconds respectively and they start tolling at the same time.

Then, the first bell tolls after every 2, 4, 6 secs…..

⇒ The second bell tolls after every 5, 10, 15 secs

So, they toll together again after 10 seconds, which is the LCM.

∴ They toll after 10 seconds, that is whenever the time is a common multiple of 2 and 5 both.

Since the bells start tolling together, the first toll also needs to be counted, that is the number of times of tolling since the first time.

D. 75 m

Solutions

Given:

Distance between two walls = 100 m

Concept:

The longer stair will be AC as the corresponding side making the smaller angle is larger than that of making bigger angle.

Calculation:

Let the height of each of the walls = h

BC + CE = BE = 100

⇒ CE = 100 – BC …….(1)

In triangle ABC, AB/BC = tan 30°

⇒ h/BC = 1/√3

⇒ BC = √3h…….(2)

In triangle CDE, DE/CE = tan 60°

⇒ h/(100 – BC) = √3

h/(100 – √3h) = √3

h = 100√3 – 3h

4h = 100√3

h = 25√3 m …… (3)

By (2) and (3)

BC = √3h = √3 × 25√3

⇒ BC = 75 m

Again in triangle ABC, BC/AC = cos 30°

⇒ 75/AC = √3/2

⇒ 150 = √3 × AC

⇒ AC = 150/√3

⇒ AC = 150/√3 ×√3/√3

∴ AC = 50√3 m

Alternate Method By Ratio Method

3 + 1 = 4 = 100 m

⇒2√3=1004×2√3

AC = 50√3

Camels can walk four kilometres per hour through the hot desert.
They can survive up to 15 days without water.
Camel humps can contain up to nearly 80 pounds of fatty tissue.
They store fat in their humps and this fat helps them to go on without water.
Since deserts are water-scarce places and the loose soil restricts any form of transport, the camel is considered the ship of the desert because it helps people to carry their stuff from one corner to another.

68. 4% more is gained by selling a table for Rs. 1,800 than by selling it for Rs. 1,750. What is its cost price?

A. Rs. 1,250

B. Rs. 12,500

C. Rs. 125

D. Rs. 50
