In moist air carbonyl dibromide is slowly hydrolyzed: $\ce{Br2CO(g) + H2O(g) -> CO2(g) + 2HBr(g)}$

(i) Suggest a method of monitoring the progress of this reaction at constant temperature so that its rate can be determined. (ii) Outline two reasons why a…

The reaction between sodium thiosulfate and hydrochloric acid was carried out at several temperatures to determine its activation energy. A graph of $\ln k$ against $\dfrac{1}{T}$ was plotted from the processed data, and the gradient of the line of best fit…

The forward reaction is first order with respect to cyclohexane. $\ce{C6H12(g) <=> C6H6(g) + 3H2(g)}$ (i) Sketch a graph showing how the rate varies with the concentration of cyclohexane. (ii) Deduce the reaction's rate equation, and state the units of the…
