Please help I'll give you a medal if you answer right
The rate law for a hypothetical reaction is rate = k [A][B]. If the concentrations of A and B are both 0.020 moles per liter and k = 1.3 × 101 M1s1, what is the reaction rate?
4.0 × 103 M
1.3 × 101 M1s1
5.2 × 105 Ms1
5.2 × 105 Ms1

Best ResponseYou've already chosen the best response.0You have k[a][b] = r You know that your concentration of a = b so that's 0.020 M (0.020)(0.020) M*M = 4x10^4 M^2 4x10^4 M^2*(1.30x10^1)M^1s^1 = 5.2x10^5 M s^1 which is your answer.
