Question

According to the rate law (rate = k[a]m[b]n), what does the rate of a reaction depend on?

Answer 1

concentration of the reactant,pressure,surface
 area of the reactant  and temperatur

Answer 2

The rate of a reaction is   = 0.12 mol.L^-1.S^-1

when we have K = 1 x 10^-2

[A] = 2 M & [B] = 3M

m= 2 & i = 1

So when the rate = K[A]^m [B]^i

When we have m + i = 3 so the order of this reaction is 3 So the unit of K is L^2.mol^-2S^-1

So by substitution:

Therfore the rate = (1x 10 ^-2 L^-2.mol^-2S^-1)*(2 mol.L^-1)^2*(3mol.L^-1)

The rate of a reaction is = 0.12 mol.L^-1.S^-1
