Solution

Q.
The rate constant of the reaction $A \to B$ is $0.6 \times 10^{- 3}$ mol $L^{- 1}$ $s^{- 1}$ . If the concentration of A is 5 M, then concentration of B after 20 minutes is [2015]

1 3.60 M

2 0.36 M

3 0.72 M

4 1.08 M

Ans.
(3)

Reaction is of zero order as the unit of rate constant is mol $L^{- 1}$ $s^{- 1}$ .

Concentration of $B = k \times t = 0.6 \times 10^{- 3} \times 20 \times 60 = 0.72$ $M$
