Q.
If a certain reaction is first order with respect to $A,$ second order with respect to $B$ and zero order with respect to $C$ then what is the order of reaction?
A) First
B) Second
C) Third
D) Zero
Explanation
(c)
Rate law $\frac{dx}{dt} = k\lbrack A\rbrack^{1}\lbrack B\rbrack^{2}\lbrack C\rbrack^{0} = k\lbrack A\rbrack^{1}\lbrack B\rbrack^{2}$
Hence, order of reaction $= 1 + 2 = 3$
