At T(K) if the rate constant for a zero order reaction is `2.5xx10^(-3)ms ^(-1)` the time required for the intial concentration of reactant ,R to fall from 0.10 M to 0..75 M at the same temperature in seconds is

A

25

B

5

C

10

D

20

Text Solution

Verified by Experts

The correct Answer is:
C
` t= ([R_(o)]-[R]_(E))/(K)= " "t= (0.1-0.075)/(2.5xx10^(-3))= (0.025)/(2.5xx10^(-3)) t= 0.01xx10^(3)=10s`
