Consider a general reaction
aA + bB   ®   cC + dD
where a, b, c and d are the stoichiometric coefficients of reactants
and products The rate expression for this reaction is
Rate µ [A]
x  [B]
y
(3 4)
where exponents x and y may or may not be equal to the
stoichiometric coefficients (a and b) of the reactants Above equation
can also be written as
Rate = k [A]
x  [B]
y
