state the factors that affect the rate of a reaction explain in detail
Answers
Answer:
There 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. ...
•Physical state of the reactants and surface area. ...
•Temperature. ...
•Presence of a catalyst.

To gain an understanding of the four main factors that affect reaction rate.
Reaction kinetics is the study of the rate of chemical reactions, and reaction rates can vary greatly over a large range of time scales. Some reactions can proceed at explosively fast rates like the detonation of fireworks (Figure 17.1 “Fireworks at Night Over River”), while others can occur at a sluggish rate over many years like the rusting of barbed wire exposed to the elements (Figure 17.2 “Rusted Barbed Wire”).
Figure 17.1. Fireworks at Night Over River
The chemical reaction in fireworks happens at an explosive rate.[1]
Figure 17.2. Rusted Barbed Wire
The rusting of barbed wire occurs over many years.[2]
Collision Theory
To understand the kinetics of chemical reactions, and the factors that affect kinetics, we should first examine what happens during a reaction on the molecular level. According to the collision theory of reactivity, reactions occur when reactant molecules “effectively collide.” For an “effective collision” to occur, the reactant molecules must be oriented in space correctly to facilitate the breaking and forming of bonds and the rearrangement of atoms that result in the formation of product molecules (Figure 17.3 “Collision Visualizations“).
