The rate of a reaction between hydrochloric acid and calcium carbonate can be increased by heating the solution. Explain why, using ideas about collisions between particles.

The graph shows the volumes of carbon dioxide given off when marble chips are reacted with hydrochloric acid in five different experiments.
Curve A shows the volume of carbon dioxide given off when some marble chips are reacted with an excess of 1.0 mol/dm3 hydrochloric acid.
Explain which curve, B, C, D or E, could represent the results obtained if half the mass of marble chips is used with excess of the acid.

Suggest a suitable piece of apparatus for collecting the carbon dioxide in this experiment.

Explain, in terms of the particle collision theory, why the rate of reaction decreases over time.

Catalysts are used to ____ __ a reaction to increase the rate at which a product is made or to make a process ________. They are not normally ___ __ in a reaction and they work by lowering the ______ energy needed for the reaction, providing a different _______ for the reaction to follow.
An example of a catalyst is a biological catalyst called an _______.
