What do understand by the rate law and rate constant of a reaction? Identify the order of a reaction if the units of its rate constant are:
(i) L-1 mol s-1 (ii) L mol-1 s-1
The rate of reaction is found to depend on concentration of term of reactant A and concentration term of reactant B
Then Rate of reaction
or Rate = K
This expression is called Rate law.
'K' in this expression is called Rate constant.
Rate constant's unit:
(i) Unit= L-1 mol s-1 Zero order reaction
(ii) Unit=L mol-1 s-1 Second order reaction.
