The rate constant of a reaction is given...

The rate constant of a reaction is given by `k = 2.1 xx 10^(10) exp(-2700//RT)`. It means that

A

log k vs. `1//T` will be a straight line with slope
`=-(2700)/(2.303" R")`

B

log k vs. `1//T` will be a straight line with intercept on log k axis `=2.1xx10^(10)`

C

The number of effective collisions are `2.1xx10^(10)" cm"^(-3)" sec"^(-1)`

D

Half life of the reaction increases with increase of temperature.

Text Solution

Verified by Experts

The correct Answer is:
A, B
is wrong because frequency factor gives total number of collicions and not effective collisions `cm^-3 sec^-1`.
(d) is wrng because half - life of the reactions decreases with incerease of temperature ( as reaction becomes faster ).
