Reactivity 2. How much, how fast and how far?

Chemistry syllabus topic from the 2025 structure/reactivity roadmap.

Find reaction rate from a gas-volume graph Read two points off a volume-of-gas vs time graph and calculate the average rate of reaction as volume produced over time (the gradient). Find reaction rate from an amount-time graph Read two points off an amount-of-product vs time graph and find the rate of reaction as amount over time (the gradient). Find the rate of mass loss from a graph Read two points off a mass-lost vs time graph and find the rate of mass loss as mass over time (the gradient). Balance equations and use mole ratios Identify limiting reactants and theoretical yield Use concentration, titration, and solution stoichiometry Explain collision theory and rates of reaction Interpret rate graphs and experimental rate data Use equilibrium constants and reaction quotients Apply Le Chatelier reasoning to equilibrium systems
