Rate constant is equal to the rate of reaction when molar conc, of reactants is unity. Its
unit depends upon order of reaction.
A reactant has a half-life of 10 minutes.
(i) Calculate the rate constant for the first order reaction.
(ii) What fraction of the reactant will be left after an hour of the reaction has occurred?

Answer:
Explanation:
This is a zero order reaction
1) t1/2=a0/2k=1/2k
2) half life is 10 mins in one hour 6 half lives takes place so 1/64th part is completed so the remaining part is 1-1/64=63/64
