To convert diamond into graphite, high amount of activation energy is required. Thus, the rate of conversion of diamond to graphite is so slow that the change is not perceptible. Therefore, diamond cannot be converted into graphite under ordinary conditions.
(A)→(ii)
Instantaneous rate is the rate at any particular point in time. It is defined as the change in concentration of the components of a reaction in a very small interval of time.
(B)→(i)
The average rate of a reaction is defined as change in concentration of the components of reactants over a time period. The time interval is large to get the average value of the change in concentration of a product or a reactant.
(C)→(iii)
Hence , the correct amtch is:
(A)→(ii),(B)→(i),(C)→(iii).
