How can one increase the rate of a chemical reaction? a. decrease the concentration of the reactants. b. add a catalyst. c. increase the activation energy needed. d. increase the entropy of the reactants. e. cool the reactants.

b. Add a catalyst.

Explanation:

Only B is correct.

The factors that affects the rate of chemical reactions are:

The rate of chemical reaction is a measure of the speed of the reaction.

When a foreign body is added to a reaction, the speed can be influenced. If the body increases the reaction rate, it is a positive catalyst. Catalysts are used to reduce the reaction time of many reactions.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
