It takes 10 min for the decomposition of...

It takes 10 min for the decomposition of 50% `H_(2)O_(2)`. If the reaction is of first order, the rate constant will be

A

0.693 per min

B

0.00693 per sec

C

0.0693 per min

D

6.93 per sec

Text Solution

Verified by Experts

The correct Answer is:
C
For first order reaction,
`k=0.693/(t_(1//2))k=0.693/(10 "min")`
`:.k=0.693` per min
