Which equation is an expression of the rate law?

Answer: [tex]Rate=k[A]^m[B]^n[/tex]
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
[tex]Rate=k[A]^m[B]^n[/tex]
k= rate constant
m = order with respect to A
n = order with respect to B
Total order = m+n
[tex]PV=nRT[/tex] is ideal gas equation
[tex]k=Ae^\frac{-E_a}{RT}[/tex] is vant hoff equation.
[tex]K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}[/tex] is equilibrium constant.
