Le Chatelier's Principle

Q.

In the following reversible reaction $2S{O}_2+O_2\rightleftharpoons 2S{O}_3+QCal$

Most suitable condition for the higher production of $S{O}_3$ is

1. High temperature and high pressure

2. High temperature and low pressure

3. Low temperature and high pressure

4. Low temperature and low pressure

Q.

For the reaction $2NO\left(g\right)\rightleftharpoons N_2\left(g\right)+O_2\left(g\right),\Delta H=-180kJmo{l}^{-1}$. Which of the following facts does not hold well?

1. The pressure changes at constant temperature do not affect the equilibrium constant

2. The volume changes at constant temperature do not affect the equilibrium constant

3. The dissociation of NO is favored more at high temperature

4. The dissociation of NO is favored less at high temperature

Q. The values of $K_{p}1$and $K_{P}2$ for the reactions
$X\leftrightharpoons Y+ZandA\leftrightharpoons 2B$ Are in the ratio of $9:1.$ If the degree of dissociation of $XandA$ be equal, then total pressure at equilibrium $\left(1\right)and\left(2\right)$ are in the ration

1. 3:1
2. 1:9
3. 36:1
4. 1:1
