The integrated rate law allows chemists to predict the reactant concentration after a certain amount of time, or the time it would take for a certain concentration to be reached. The integrated rate law for a first-order reaction is: [A]=[A]0e−kt[A]=[A]0e−kt Now say we are particularly interested in the time it would take for the concentration to become one-half of its initial value. Then we could substitute [A]02[A]02 for [A][A] and rearrange the equation to: t1/2=0.693k t1/2=0.693k This equation calculates the...

1.The reaction of hydrogen and nitric oxide, shown below, is first order with respect to hydrogen and second order with respect to nitric oxide. Write the rate law for this reaction. (Rate expressions take the general form: rate = k . [A]a . [B]b.) 2 H2(g) + 2 NO(g) → N2(g) + 2 H2O(l) The rate law for a general reaction involving reactant A is given by the equation rate = k[A]2, 2. Where rate is the rate of the...

The integrated rate law allow chemists to predict the reactant concentration after a certain amount of time, or the time it would take for a certain concentration to be reached. The integrated rate law for a first-order reaction is: [A] = [A]oe -Rt Now say we are particularly interested in the time it would take for the concentration to become one-half of its initial value.
