Choose from the options given below, the correct one regarding order of reaction is :
Choose from the options given below, the correct one regarding order of reaction is :
(b) Zero order (c) and (e) First order
(a) and (b) Zero order (e) First order
(b) and (d) Zero order (e) First order
(a) and (b) Zero order (c) and (e) First order
Explanation
For Zero order reactions
rate = K [Reactant]0
$$\Rightarrow$$ r = k

For First order reaction $$\to$$
r = K [Concentration]
