Question

79. The rate constant of a zero order reaction is
0.2 mol dm-3 h-1 If the concentration of the reactant
after 30 minutes is 0.05 mol dm3. Then its initial
concentration would be :-
(1) 6.05 mol dm-3
(2) 0.15 mol dm-3
(3) 0.25 mol dm-3
(4) 4.00 mol dm-3​

Answer 1

Answer:

The rate constant of a zero order reaction is

0.2 mol dm-3 h-1 If the concentration of the reactant

after 30 minutes is 0.05 mol dm3. Then its initial

concentration would be :-

(1) 6.05 mol dm-3

(2) 0.15 mol dm-3

(3) 0.25 mol dm-3

(4) 4.00 mol dm-3
