Question
The rate constant of a reaction is given by k = 2.1 × 1010 exp(-2700/RT). It means that
Options
A. log k versus 1/T will be a straight line with slope = 
B.log k versus 1/T will be a straight line with intercept on log k axis = 2.1 × 1010.
C.The number of effective collisions are 2.1 × 1010cm-3s-1.
D.Half life of the reaction increases with increase of temperature.
Solution
For Arrhenius equation k = Ae-Ea/RT
= 2.1 × 1010 × e-2700/RT
or
log k = log A -
= log 2.1 × 1010 - 
Plot of log k vs 1/T
= 2.1 × 1010 × e-2700/RT
or
log k = log A -
= log 2.1 × 1010 - Plot of log k vs 1/T
