Rate of Reaction

Rate of Reaction

Reactions can happen at any speed, for example rusting iron is very slow, magnesium reacting with acid is moderate (it produces a gentle stream of bubbles) and a reaction with an explosion is very fast.

Rate of reaction can be affected by:

.Temperature

.Concentration (pressure for gases)

.Catalyst

.Surface area of solids (or size of solid pieces)

Graphs

A steeper slope shows a graph with a quicker reaction. When the slope becomes flat the reaction is finishing. A change in rate could be due to an increase in temperature, an increase is concentration or pressure, a catalyst being added, a solid reactant being crushed into smaller bits. The only way more products can be made is by…
