Mercury level rises in the right-hand limb, this means that the pressure in R increases.
In 1, according to Le Chartelier's Principle, a rise in temperature would favour the forward reaction, thus the equilibrium position shifts closer to the products. In the reaction, every 1 mole of reactants forms 2 moles of products. As more reactants are converted to products, the total mole number (reactant plus product) in R gets larger, so the pressure becomes higher. 1 is correct.
In 2, since the mole number of reactants and products in the reaction is the same, where the equilibrium shifts to shall have no effect on the pressure since the total mole number stays unchanged. 2 is incorrect.
In 3, there is definitely no change since the two bulbs are filled with the same gas. 3 is incorrect.
Answer is D.
bt shudnt u consider the volume of R???
