Factors That Affect The Rate Of Reaction

Factors That Affect The Rate Of Reaction. Effect of the surface area of reactants 6. The following are some of the factors that affect the average rate of a reaction.

Factors Affecting the Rate of Reaction SPM Chemistry from spmchemistry.blog.onlinetuition.com.my

Effect of the surface area of reactants 6. Rate of reaction is a measure of how quickly either reactants are used up, or products are formed, in a chemical reaction. The rate of a chemical reaction can be altered by changing the reacting conditions.
