- Use graphs to analyse the experiment results and find evidence of order of reaction.
Several experiments were run by changing the concentration of a single reactant in a chemical process, which produces a gas by-product, C:A (aq) + 2B (aq) → C (g) + D (aq)
The results below show the reaction with different concentrations of reactant A, and the time taken to obtain 10 cm3 of the gas product C.
