Draw the enthalpy diagram for exothermic and endothermic reaction.

Give an example each for exothermic and endothermic reactions.

What is the significance of the second law of thermodynamics in the spontaneity of exothermic and endothermic reactions?

The following is(are) endothermic reaction(s)

Which of the following is not an endothermic reaction?

Assertion : E_(a) of the forward reaction is higher than that backward reaction in a reversible endothermic reaction. Reason: Increasing the temperature of the substance increase the fraction of molecules which collide with energies greater than E_(a) .

Assertion : The rate of reaction whether exothermic or endothermic, increases with temperature. Reason : The rate of reaction = K [reactant] and K increases with temperature.
