We carry out two experiments involving the

reaction

2A + B → C + 2D ,

Rate = k[A]^2[B], at the same temperature. In

the second experiment the initial concentration of A is tripled and the initial concentration of B is doubled. The initial rate in the

second experiment will be how many times

that of the first?
