Question

State what the presence of an enzyme does to the activation energy for the reaction and explain why this increases the rate of reaction.

Accepted Answer

Effect of enzymes on rate of reaction:Enzymes lower the activation energyThis lowers the minimum amount of energy required in particles in order for them to reactTherefore higher proportion of particles are able to react - more reactions happen during a given time interval - higher rate
