14.4: Effect of Concentration on Reaction Rate

WebIf the concentration of reactants is increased, there are more reactant particles moving together. There will be more collisions and so the reaction rate is increased. The higher the... WebThere are four main factors that can affect the reaction rate of a chemical reaction: Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

WebThe rate at which the reaction occurs can be altered by changing the set of conditions such as: temperature, concentration, pressure, surface area and the use of catalysts (Lister and Renshaw, 2008). Simple collision theory highlights the way in which these factors affect the reaction rate on a molecular level. WebWhen this system is at equilibrium, the forward and reverse reaction rates are equal. $$\text{rate}_f=\text{rate}_r$$ If the system is stressed by adding reactant, either H 2 or I 2, the resulting increase in concentration causes the rate of the forward reaction to increase, exceeding that of the reverse reaction: $$\text{rate}_f\gt \text{rate}_r$$
