The rate of a chemical reaction was observed to rise with increasing temperature up to
temperature, tx. at temperatures higher than tx, however, the reverse was observed.
this may be explained by,
a. a reaction mechanism comprising of a complex set of elementary
reactions
b. a reaction kinetics limited by factors other than the rates of elementary
chemical reactions
c. a reaction running under equilibrium control
d. experimental error in the determination of the rates of reaction
e. none of the above
