The variables which can affect the speed of a chemical reaction are inihibitor, concentration, temperature and particle size.
What is the speed of reaction?
Speed of any reaction also known as rate of reaction and it gives idea about the duration that at how much time it will complete.
- Addition of inhibitor slows down the speed of the reaction as inhibitor blocks the activity of the reactants.
- Change in concentration of reactant also chnages the speed of the reaction because it completely depends on the reactant concentration.
- Temperature changes also affect the speed of the reaction as it changes the kinetic property of the reaction.
- Particle size provides the surface area to get react so changes in this property will also changes the speed of the reaction.
Hence all of the above will changes the speed of the reaction.
