What is the order with respect to each of the reactant and overall order of the following reactions ?
(a) `5Br_((aq))^(-)+BrO_(3(aq))^(-)+6H_((aq))^(+)rarr3Br_(2_((l)))+3H_2O_((I))`
The experimental rate law is
Rate `=k[Br^(-)][BrO_3^-][H^+]^2`

(b) `CH_3CHO_((g))overset(Delta)rarrCH_(4(g))+CO_((g))`
the experimental rate law is
Rate `=k[CH_3CHO]^(3//2)`

Explanation

(a) First order with respect to `Br^-` , first order with respect to `BrO_3^-` and second order with respect to `H^+` . Hence the overall order of the reaction is equal to
(b) Order of the reaction with respect to acetaldehyde is `3/2` and overall order is also `3/2` .
