Question

Which of the following factor(s) will increase the speed of a chemical reaction? O Adding a catalyst O Raising the concentrations of reactants Increasing the temperature of the reaction Increasing the frequency of collisions between reactants All of the above

Answer 1

1) It is true, the catalyst is added to enhance the rate of reaction.Which decrease the activation energy.

2) It is true that in general the reaction rate increases when raising the concentration of reactant.

3) this is true that by increasing the temperature of reaction the rate of chemical reaction can be increased.

4) This is true that more the collision more will be interaction and more will be rate of reaction.

Therefore, choose all of the above option.

Hence option (v) is correct answer.
