Discuss the effect of concentration and temperature on reaction rates.

A: Coenzymes are usually proteins R:The term feedback refers to the effect of enzyme concentration on its rate of reaction.

What does the graph indicate ? The graph given below shows the effect of substrate concentration on the rate of reaction of the enzyme green- gram-phos-phatase.

Discuss the effect of temperature on the rate of a reaction.

What is the effect of catalyst on the rate of reaction ?

Discuss the effect of temperature on the spontaneity of a process.

Discuss the effect of temperature on the equilbrium constant. How does it change for (a) exothermic reaction (b) endothermic reaction (c) reaction having zero heat of reaction?

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. If the rate of reaction doubles for 10^(@)C rise of temperature form 290K to 300K, the activation energy of the reaction will be approximately :

The Arrhenius equation expressing the effect of temperature on the rate constant of a reaction is given as
