Edexcel GCSE Chemistry Calculations
This page covers the following topics:
Amount of product gained or amount of reactant lost can be used to calculate the rate of reaction and draw graphs to represent its change.
These graphs can be produced from data sets acquired during practical experiments. Remember when calculating rate of reaction time should be in seconds.
The rate of reaction of an experiment is given by the gradient of its graph by finding the change in the mass or the volume of the reactants used or products used per unit time.
Draw a graph to show the impact of increasing temperature on the reaction between zinc and hydrochloric acid. There should be two lines on your graph, one for low temperature and one for high temperature.
