Question

The rate constant of the relation $A\to B$ is $0.6\times {10}^{-3}$ mole per second. If the concentration of $B$ after $20$ minutes is :

• A. $0.36$ M
• B. $0.72$ M
• C. $1.08$ M
• D. $3.60$ M

Answer 1

Answer: (B)

$0.72$ M

By unit of rate constant it is clear,that the $reaction$ is zero order.

$\therefore \left[B\right]=k\times t$

$=0.72M$
