Question

The rate of chemical reaction at constant temperature is proportional to

Answer 1

At a constant temperature, the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants.

Answer 2

The rate of a chemical reaction at constant temperature is directly proportional to the concentration of the reactants.

• This means that as the concentration of the reactants increases, the rate of the reaction also increases.
• The rate of a chemical reaction is also affected by the presence of a catalyst, which can increase the rate of the reaction by providing an alternative pathway for the reaction to occur.
• The rate of a chemical reaction may also be affected by the physical state of the reactants, with reactions occurring more quickly when the reactants are in the form of gases or finely divided solids.
• Finally, the rate of a chemical reaction can be affected by the surface area of the reactants, with reactions occurring more quickly when the reactants have a larger surface area exposed to each other
