What is meant by Order of the Reaction?
rate = k(conc A)The power(m) to which the concentration of A is raised in the rate expression
describes the order of the reaction.
. If "m" = 0, the reaction is zero order
. if "m" = 1, it is first
Integrated Rate Laws
The differential rate law describes how the rate of reaction varies with the
concentrations of various species, usually reactants, in the system. The rate of
reaction is proportional to the rates of change i
Differential Rate Laws
In many reactions, the rate of reaction changes as the reaction progresses'
Initially the rate of reaction is relatively large, while at very long times the rate
of reaction decreases to zero (at whi
