When ln k is plotted against 1/T, the slope was found to be -10.7 × 103 K, activation energy for the reaction would be :
The rate of a reaction doubles when its temperature changes form 300 K to 310 K. Activation energy of such a reaction will be (R=8.314 JK−1 mol−1 and log 2=0.301)
For the reaction A+B→C+D ΔH=−20 kJ mol−1 . The activation energy of the forward reaction is 85kJ mol–1. The activation energy for backward reaction is
The rate of a reaction doubles when its temperature changes from 300 K to 310 K. Activation energy of such a reaction will be:
