Question 1
1 / -0

Half life (t₁) of the first-order reaction and half life (t₂) of the second-order reaction are equal. Hence, assuming [A]₀ to be same, the ratio of the rate at the start of the reaction (assuming same initial concentration of the reactant in both the reactions) would be

A
1

B
2

C
0.693

D
1.44
Question 2
1 / -0

Consider a gaseous reaction, the rate of which is given by K[A] [B], the volume of the reaction vessel containing these gases is suddenly reduced to 1/4^th of the initial volume. The rate of reaction relative to the original rate would be

A
16/1

B
1/16

C
8/1

D
1/8

Solution

By reducing volume to 1/4 th the concentration will become 4 times hence rate 16 times.
Question 3
1 / -0

During the particular reaction 10% of the reactant decompose in one hour 20% in two hours 30% in three hours and so on. The unit of the rate constant is

A
Hour^–1

B
L mol^–1 hour^–1

C
mol L^–1 hour^–1

D
mol hour^–1

Solution

This reaction is a zero order reaction.
