Rate law with rate constant

Gives the rate of a chemical reaction as the rate constant, which depends on temperature, times the concentrations of reactants A and B raised to their reaction orders m and n. It is used in chemical kinetics to relate measured reaction speed to reactant concentrations.

r = k(T)[\mathrm{A}]^m [\mathrm{B}]^{n}

What the symbols mean

reaction rate (mol per litre per second)
rate constant, which depends on temperature T
concentration of reactant A (mol per litre)
concentration of reactant B (mol per litre)
reaction order with respect to A
reaction order with respect to B
