Each question contains STATEMENT-1 (Assertion) and STATEMENT-2( Reason).
Examine the statements carefully and mark the correct answer according to the instruction given below:
STATEMENT-1:The gas phase reaction `PCl_(3)(g)+Cl_(2)(g) iffPCl_(5)(g)` shifts to the right on increasing pressure.
STATEMENT-2: When pressure increase, equilibrium shifts towards more number of moles.

A

If both the statements are TRUE and STATEMENT-2 is the correct explanation of STATEMENT-1

B

If both the statement are TRUE but STATEMENT-2 is NOT the correct explanation of STATEMENT-1

C

If STATEMENT-1 is TRUE and STATEMENT-2 is FALSE

D

If STATEMENT-1 is FALSE and STATEMENT-2 is TRUE

The correct Answer is:
To solve the question, we need to analyze both statements provided: **Step 1: Analyze Statement 1 (Assertion)** - The reaction given is: \[ \text{PCl}_3(g) + \text{Cl}_2(g) \iff \text{PCl}_5(g) \] - In this reaction, we have 2 moles of gas on the reactant side (1 mole of PCl3 and 1 mole of Cl2) and 1 mole of gas on the product side (1 mole of PCl5). - According to Le Chatelier's principle, when the pressure is increased, the equilibrium will shift towards the side with fewer moles of gas. - Since there are 2 moles of gas on the reactant side and 1 mole on the product side, increasing the pressure will shift the equilibrium to the right (towards PCl5). **Conclusion for Statement 1:** - Statement 1 is **correct**; the reaction shifts to the right on increasing pressure. **Step 2: Analyze Statement 2 (Reason)** - Statement 2 claims: "When pressure increases, equilibrium shifts towards more number of moles." - This statement contradicts Le Chatelier's principle, which states that an increase in pressure will shift the equilibrium towards the side with fewer moles of gas. - Therefore, this statement is **incorrect**. **Conclusion for Statement 2:** - Statement 2 is **incorrect**; the equilibrium does not shift towards more moles when pressure increases. **Final Answer:** - Statement 1 is true, and Statement 2 is false. Therefore, the correct answer is **C**. ---
