The graph shows the percentage yield of a product in a gaseous equilibrium under different conditions. The forward reaction in the equilibrium is A exothermic with the number of moles of gas decreasing. B exothermic with the number of moles of gas increasing. ☒ C endothermic with…
Kinetic data obtained from the hydrolysis of halogenoalkanes gives insight into the mechanisms of the reactions. (a) Draw the structural formulae of a primary, a secondary and a tertiary iodoalkane, each with four carbon atoms and one iodine atom. (2) (b) The halogenoalkane, 1-br…
The kinetics of the reaction between hydrogen peroxide and iodide ions in the presence of sulfuric acid is investigated. $$ \mathrm{H_{2}O_{2}(aq)}~+~2\mathrm{H^{+}(aq)}~+~2\mathrm{I^{-}(aq)}~\rightarrow~2\mathrm{H_{2}O(l)}~+~\mathrm{I_{2}(aq)} $$ (a) First, the concentration of…
