Rate of reaction
Rate of reaction What factors affect the rate of reaction? Factors: The temperature can affect the rate of a reaction Concentration affects the rate of the reaction because the level of the hydrochloric acid is higher A catalyst is needed for the reaction to speed up The surface area increases the space for the molecules to increase the rate of the reaction Background knowledge: Temperature: At low temperatures, particles of reacting substances do not have much energy. ... Concentration: Rate increases with concentration if the concentration of the acid is increased the reaction goes faster because in dilute acid there are not many acid particles. ... Surface area: A reaction between magnesium and acid would be much faster if the metal was to be powdered. ... Catalyst: A catalyst speeds up a reaction, only some can be done like this not all reactions with a catalyst a collision needs less energy to become successful. The result will be that more collisions are more successful so the reaction is now faster.
