# NEET Chemistry Chemical Kinetics Questions Solved

(a) For a first order reaction, show that time required for 99% completion is twice the time required for the completion of 90% of reaction.

(b) Rate constant 'k' of a reaction varies with temperature 'T' according to the equation :

log k = log A -

where Eis the activation energy. When a graph is plotted for log k vs.$\frac{1}{T}$, a straight line wih a slope of -4250 K is obtained. Calculate 'E' for the reaction.(R = 8.314 JK-1 mol-1 )
