Some chemical substance reactions are s pitiable, such as rusting, and nigh are unwavering, like burning. The lay out of reaction depends on the temperature and parsimoniousness of the reactants, and the surface area of any solid reactants.
The rate of reaction can be found by measuring the measuring of reactant used up, or the amount of product formed, in a apt(p) time. Catalysts accession the rate of a reaction without organism changed themselves by the end of the reaction.
Different reactions can happen at different rates. Reactions that occur slowly take aim a low rate of reaction. Reactions that happen quickly have a exalted rate of reaction. For example, rusting is a slow reaction: it has a low rate of reaction. Burning and explosions are very fast reactions: they have a high rate of reaction.
For a chemical reaction to occur, the reactant particles must collide. But collisions with too little readiness do not produce a reaction. The particles must have enough energy for the collision to be prosperous in producing a reaction. The rate of reaction depends on the rate of successful collisions between reactant particles.
The more successful collisions there are, the windy the rate of reaction.
A catalyst is a substance that can increase the rate of a reaction. The catalyst itself remains unchanged at the end of the reaction it catalyses. Only a very broken amount of catalyst is needed to increase the rate of reaction between large amounts of reactants. Different catalysts catalyse different reactions. The faster the rate, the more reactant is used, or product is made, in a given time. The faster the reaction, the steeper the line on a interpret showing total product against time will be.
