The rate of a chemical reaction

increases as the reaction proceeds

decreases as the reaction proceeds

may increase or decrease during the reaction

remains constant as the reaction proceeds

Enzymes enhance the rate of reaction by

Forming a reactant product complex

Enanging the equilibrium piont of the reaction

Combining with the product as soon as it is formed

Lowering the activation energy of the reaction

A reaction has both DeltaH and DeltaS negative.The rate of reaction

Increases with increase of temperature

Increases with decrease of temperature

Remains unaffected by change of temperature

Cannot be predicted for change in temperature
