Solution
In chemistry, there are several chemical reactions that occur in several conditions. Each reaction has its specific property, during these reactions both usable and non-usable products are produced.
Complete step by step answer:
Before matching the given list, let's have a look at these mentioned reactions.
As we know that there are four laws of thermodynamics that are told about the physical qualities like temperature, heat, entropy, and work.
Zeroth - It tells about that temperature is a very important factor in a thermodynamic system
First law - It tells about the energy that is total energy is constant in a system, it changes in one form to another.
Second law - It tells about the irreversibility of processors; it defines spontaneous and non-spontaneous reactions.
Third law - It tells about entropy and constant temperature.
Spontaneous process - A reaction that favors the production of the product or when the rate of forward reaction is greater than the rate of backward reaction.
Non Spontaneous - A reaction that does not support the production of the product in the given condition.
Equilibrium - the rate of the forward reaction is equal to the rate of backward reaction.
(a) Kp>Q
It shows that the rate of the forward reaction is greater than the rate of backward reaction which means it is a spontaneous reaction. Therefore, (a) matches with (iv).
(b) ΔGO<RT In Q
It shows that ΔGO is positive which means the reverse reaction is feasible, so it is a non-spontaneous reaction. Therefore (b) matches with (i).
(c) Kp=Q
It shows that the rate of the forward reaction is equal to the backward reaction which means It is an equilibrium reaction. Therefore, (c) matches with (ii).
(d) T>ΔSΔH
It shows that when ΔH is negative then ΔG will be positive which means the reaction is spontaneous and endothermic. Therefore, (d) matches with (iii).
According to these points, option (C) is the correct answer.
Note:
Endothermic reaction - A reaction in which the reactant absorbs the heat from the surrounding and produces the product. In this reaction the entropy of the surrounding area decreases. Exothermic reaction- A reaction releases heat during the reaction. In this reaction the entropy increases.
