6.3 Rate Laws and Order of Reaction
The Rate Law – the rate (r) will always be
proportional to the product of the initial
concentrations of the reactants, where these concentrations are raised to some
exponential values, this can be expressed as
r is proportional [X]^m[Y]^n
m & n are exponents that describe the relationship between the rate and the initial
concentrations
Rate Law Equation
Where k is the rate constant – determined through experimental testing
Order of reaction – the exponent value that describes the initial concentration
dependence of a particular reactant
If exponent = 0 then changing the concentration will not affect the rate of reaction
Exp= 1,
reaction will double if concentration is doubled
