Rate of Reaction
Graphs can be produced which show the rate of reaction. The Steeper the gradient of a line, the faster the reaction. If the line appears to be "horizontal", then this shows the reaction to be complete i.e. finished.
The factors affecting the rate of reaction will affect the shape/gradient of a line graph. If the same quantities of chemicals are used every time, the graph should always reach the same end point. However, if one of the chemicals is, for example, doubled (i.e concentration, mass) then the graph will reach double the height. Similarly, a hotter temperature OR using smaller particles will produce a steeper graph, ending at the same height.
Equation to remember -
Average rate = Change in measurement/Change in time
