Multiple CHOICE, Chose the one alternative that best completes the statement or answers the question. Molecular hydrogen can be made from methane gas by the reaction below. How is the rate of disappearance of CH_4 related to the rate of appearance of H_2? - Delta [CH_4]/Delta t = ? CH_4 (g) + H_2O (i) rightarrow CO (g) + 3H_2 (g) + 1 Delta [H_2]/3 Delta t +3 Delta [H_2]/Delta t + Delta [H_2]/Delta t none of these. For a reaction that follows the general rate law, Rate -K [A] [B]^2, what will happen to the rate of reaction if the concentration of A is increased by a factor of 3.00? the rate will decrease by a factor of 1/9.00. Decrease by a factor of 1/3.00. Increase by a factor of 9.00. increase by a factor of 3.00. What is the overall reaction order for the reaction that has the rate law: Rate -k [H_2] [NO]^2? zero order first order second order third order. the following set of data was obtained by the method of initial rates for the reactions: (H_3 C)_3 CBr + OH rightarrow (H_3 C)_3 COH + Br^- what is the order of reaction with respect to ion, OH? zero first second none of these Which statements below regarding the half - life of a zeroth - order reaction is true? Each half-life is four times as long as the preceding half-life. The half-life remains unchanged throughout the course of the reaction. Each half-life is half as long as the preceding hall-life. Each half-life is twice as long as the preceding half-life. For a particular first-order reaction, it takes 2880 seconds for the concentration of the reactant to decrease from 20M to .50 M. What is the value for rate constant (in s^-1) for the reaction? 2.9 times 10^-2 s^-1 1.0 times 10^-4 s^-1 6.0 times 10^-3 s^-1 4.8 times 10^-4 s^-1. the rate constant, k, for a first-order reaction is equal to 4.2 times 10^-2 s^-1. What is the half-life for the reaction? 2.9 times 10^-4 s 1.7 times 10^3 s 1.2 times 10^3 s 2.4 times 10^3 s
