CHXII04:CHEMICAL KINETICS

320515 For a reaction \(\mathrm{A} \rightarrow \mathrm{B}\), the rate increases by a
factor of 2.25 when the concentration of \(\mathrm{A}\)
is increased by 1.5. What is the order of the
reaction?

320516 For a reaction \(\mathrm{A}+\mathrm{B} \rightarrow \mathrm{C}+\mathrm{D}\) if the concentration of A is doubled without altering the concentration of \(B\), the rate gets doubled. If the concentration of \(\mathrm{B}\) is increased by nine times without altering the concentration of \(\mathrm{A}\), the rate gets tripled. The order of the reaction is

320518 One proposed mechanism of the reaction of HBr with \(\mathrm{O}_{2}\) is given here
\({\rm{HBr}} + {{\rm{O}}_{\rm{2}}} \to {\rm{HOOBr}}\quad \quad \quad \,\,({\rm{slow}})\)
\({\rm{HOOBr}} + {\rm{HBr}} \to 2{\rm{HOBr}}\;\quad \,\,({\rm{fast}})\)
\({\rm{HOBr}} + {\rm{HBr}} \to {{\rm{H}}_{\rm{2}}}{{\rm{O}}_{\rm{2}}} + {\rm{B}}{{\rm{r}}_{\rm{2}}}\quad ({\rm{fast}})\)
