- Understand how to determine the rate of a chemical reaction by measuring the quantity of a reactant used or the quantity of product formed over time.
- Calculate the mean rate of a chemical reaction using the equations:
mean rate of reaction=time takenquantity of reactant used
mean rate of reaction=time takenquantity of product formed
- Describe the quantity of a reactant or product using units of mass (grams) or volume (cm³).
- Express the units of the rate of reaction properly as g/s or cm³/s.
- (Higher Tier only) Calculate the quantity of reactants in terms of moles and express the rate of reaction in mol/s.
- Calculate the mean rate of a reaction from provided data regarding reactant usage, product formation, and time elapsed.
- Draw and interpret scientific graphs that plot the quantity of product formed or reactant used up against time.
- Draw accurate tangents to curves on reaction graphs and calculate the slope of the tangent to measure the rate of reaction.
- (Higher Tier only) Calculate the exact gradient of a tangent to a curve to determine the rate of reaction at a specific point in time.
