X2 + y2 > x2y2 rate = k[x2]a reaction and its experimentally determined rate law are represented above. a chemist proposes two different possible mechanisms for the reaction, which are given below. mechanism 1 mechanism 2x2 > 2x (slow) x2 > 2x (slow)x + y2 > xy2 (fast) x + y2 > xy + y (fast)x + xy2 > x2y2 (fast) x + xy > x2y (fast)x2y + y > x2y2 (fast)based on the information above, which of the following is true? both mechanism 1 and 2 are consistent with the rate law. only mechanism 2 is consistent with the rate law. neither mechanism 1 nor mechanism 2 is consistent with the rate law. only mechanism 1 is consistent with the rate law.
