Question 1 (1 point) v Saved For the reaction 2A + B C, the rate of the reaction doubles if the starting concentration of A doubles, and the rate of the reaction quadruples (.e., increases four-fold) if the starting concentration of B doubles. What is the rate law? Rate=k[A][B] Rate=k[A]2[B] O Rate=k[A][B]2 Not enough information given
