For a reaction of the form, A + B + C Products, the following observations are made: tripling the concentration of A increases the rate by a factor of 27, doubling the concentration of B has no effect on the rate, and tripling the concentration of C increases the rate by a factor of 3. Write down the rate law for this reaction.
By what factor will the rate of the reaction described above change if the concentrations of A, B, and C are all halved (reduced by a factor of 2)?
a) The rate will change by a factor of 0.0625.
b) The rate will change by a factor of 0.125.
c) The rate will change by a factor of 0.5.
d) The rate will change by a factor of 0.25.
e) The rate will change by a factor of 1.
