Modelling with Functions What is a mathematical model? A?mathematical?model?simplifies a real-world situation so it can be described using mathematics which can then be used to make predictions The...
Activation Energy For a reaction to take place, the reactant particles need to overcome a minimum amount of energy This energy is called the?activation energy (Ea) In?exothermic reactions?the react...
Squared Linear Denominators Partial fractions In partial fractions the common denominator is split into parts (factors) This is the reverse process to?adding?(or subtracting) fraction...
Linear Denominators What are partial fractions? This is the reverse process to?adding?(or subtracting) fractions When adding fractions a common denominator is required In partial frac...
Measuring Rates To measure the?rate of a reaction, we need to be able to measure either how quickly the reactants are used up or how quickly the products are formed The method used for measuring de...
