(b) if both A and R are true but R is not the correct explanation of A. (c) if A is true but R is false. (d) if A is false but R is true. (e) if both A and R are false. Assertion: The endothermic reactions are favoured at lower temperature and the exothermic reactions are favoured at high 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.
