Identify giving reasons, the reaction order from each of the following rate constants: (i) k=2.3xx10^(-5)"L mol"^(-1)s^(-1)"" (ii) k=3xx10^(-4)s^(-1)

Answer»

Solution :`K=("RATE")/([A]^(n))=("CONCENTRATION")/("Time")xx(1)/(["concentration"]^(n))`
or `k=(1)/("time" xx ["concentration"]^(n-1))`
For zero order n = 0, `k=(["concentration"])/("time")"or mol L"^(-1)s^(-1)`
For first order n = 1, `k=(1)/("time"0 or s^(-1)`
For second order n = 2, `k=(1)/("time" xx["concentration"])or (1)/(s xx "mol L"^(-1))"or mol"^(-1)LS^(-1)`
THEREFORE for the reaction (i), the order = 2
and for the reaction (ii), the order = 1.
