Paper 3Theory (Core)3 marks
A student conducts an experiment to measure the effect of temperature on the rate of a reaction between sodium thiosulfate and hydrochloric acid. The results are plotted on a graph.
Description
Graph of Reaction Rate vs. Temperature
The graph shows the rate of reaction (in arbitrary units) on the y-axis and temperature (in degrees Celsius) on the x-axis. As the temperature increases, the rate of reaction also increases until it levels off at higher temperatures.
- a[3]
Analyse the graph and describe the relationship between temperature and reaction rate.
