Assertion :The endothermic reactions are favoured at lower temperature and the exothermic reactions are favoured at higher temperature. Reason: When a system in equilibrium is disturbed by changing the temperature, it will tend to adjust itself so as to overcome the effect of the change.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is D Assertion is incorrect but Reason is correct
Endothermic reactions are favoured at higher temperature as it needs the activation energy for reaction to proceed further. In case of exothermic reactions, lower temperature also can drive the reaction forward as the energy released during the subsequent reaction. This can also be explained on the basis of the Le-chatellier's principle.
So, the assertion is wrong.
Reason given is the statement of the Le-chattelier's principle

Q. Assertion: The impurities such as

{SiO}_{2}

present in iron ore is removed by

.

Reason:

CaO

formed by decomposition of

reacts with

{SiO}_{2}

to form slag.

Assertion (A) The enthalpy of reaction remains constant in the presence of a catalyst.

Reason (R) A catalyst participating in the reaction forms different activated complex and lowers down the activation energy but the difference in enrgy of reactant and product remains the same.
