For the following reaction, it is found that doubling the amount of a causes the reaction rate to quadruple while doubling the amount of b causes the reaction rate to double. what is the best rate law equation for this reaction?

a + b yields 2c

rate = k[a]2[b]
rate = k[a][b]
rate = k[a][b]2
rate = k[a]1/2[b]

That doubling the amoun of A causes the rate to quadruple means that the rate is proportional to the square of the concentration of A, i.e. [A]^2

That doubling the amount of B causes the rate to double means that the rate is proportional to the concentration of B, i.e. [B]

Then, rate = k[A]^2 [B], which is the first option.

D)can be increased in a closed system
