Observe the following statements (I) In the $\mathrm{H}_{2}-\mathrm{O}_{2}$ reaction, explosion occurs when the rate of chain branching exceeds that of chain termination. (II) The order of the reaction, $\mathrm{nA} \rightarrow$ products, is 2.5 . For this reaction, $\mathrm{t}_{1 / 2} \propto[\mathrm{A}]_{0}^{-3 / 2}$ (III) Unimolecular gas phase reactions are second order at low pressure but become first order at high pressure.
