IB Chemistry 2.2.3 Factors affecting rate Questions
Get faster at rate-factor questions by predicting how temperature, concentration, pressure, dilution and catalysts alter curves and reaction speed.
How this is tested
- predict rate increases in named cases: higher T or pressure speeds Br2 + NO, but larger volume does not
- sketch the higher-T gas-volume curve with a steeper start but the same final volume
- identify dilution as slowing Mg + HCl, or pick the more dilute HCl curve with the lower rate
