(a) The decomposition of A into products has a value of K as `4.5 xx 10^(3)s^(-1) " at "10^(@)C` and energy of activation 60kJ `"mol"^(-1)`. At what temperature would K be `1.5 xx 10^(4) s^(-1)` ?
(b) (i) If half life period of a first order reaction is x and `3//4^(th)` life period of the same reaction is y, how are x and y related to each other ?
(ii) In some cases it is found that a large number of colliding molecules have energy more than threshold energy, yet the reaction is slow. Why?
