(b) Determine the value of the rate constant k. Write an expression for the rate law.

(c) Determine the time at which [A] = 0.500 mol / L. Determine the time at which [A] = 0.250 mol / L.

(d) The half-life of a second-order reaction is not constant. Is this consistent with the times that you calculated in part (c) above? Explain.
