320106 For a certain reaction a large fraction of molecules has energy more than thresold energy, still the rate of reaction is very slow. The possible reason for this could be that

320107 Which of the following graphs represents exothermic reaction?

320108 Statement A :
To account for effective collisions another factor P is introduced.
Statement B :
In a collision, molecules must be properly oriented.

320109 For a given reaction, energy of activation for forward reaction \(\left(\mathrm{E}_{\mathrm{af}}\right)\) is \(80 \mathrm{~kJ} \mathrm{~mol}^{-1}\) and \(\Delta \mathrm{H}=40 \mathrm{~kJ} \mathrm{~mol}^{-1}\). A catalyst lowers \(\mathrm{E}_{\mathrm{af}}\) to \(20 \mathrm{~kJ} \mathrm{~mol}^{-1}\). The ratio of energy of activation for reverse reaction before and after addition of catalyst is
