Question

Mention the factors that affect the rate of a chemical reaction.

Answer 1

We have to remember that the rate of reaction alludes to the speed at which the products are formed in the reactants in a compound reaction. When we talk about chemical reactions, the rate at which they happen shifts by an incredible arrangement. Some chemical reactions are almost momentary, while others take some time to attain the final equilibrium.

Complete step by step answer:
We need to know that according to the overall definition, the speed with which a reaction happens is alluded to as the rate of reaction.
For instance, wood burning has a reaction rate that is higher since the process is quick and rusting of iron has a rate of the reaction low as the process is moderate.
The various factors which influence the rate of chemical reaction are,
1.Nature of the reaction
2.Effect of concentration
3.Effect of pressure
4.Temperature
5.Solvent
6.Order of reaction
7.Electromagnetic radiation
8.Light Intensity
9.Catalyst presence
9.Surface area of reactants
Nature of the reaction: The rate of reaction exceptionally relies upon the sort and nature of the reaction. As referenced before, not many reactions are normally quicker than others while a few reactions are very slow. The rate of reaction is for the most part more slow in fluids when contrasted with gases and more slow in solids when contrasted with fluids. Size of the reactant likewise matters a ton. The more modest the size of the reactant, the quicker the reaction.
Effect of concentration: Based on collision theory, there is an increase in reaction rate with respect to the rise in the reactant concentration.
Pressure: Pressure builds the concentration of gases which thus brings about the expansion of the reaction rate. The reaction rate increments toward less vaporous atoms and diminishes the opposite way.

Note: We need to remember that the higher Temperature also increases the rate of the reaction. The reaction rate is highly affected by the solvent properties and ionic strength. When a catalyst is present, the speed of the reaction raises the reaction speed. Rate of the reaction is also affected by the surface area of the reactants. If the surface area is more, the speed of the heterogeneous chemical reactions increases.
