The reaction $2SO_{2(g)} + O_{2(g)} \rightleftharpoons 2SO_{3(g)} + q$ is favored by:

Which of the following equilibria will shift to the right side on increasing the temperature?

The binding of oxygen by haemoglobin $(Hb)$ forming $(HbO_2)$ is partially regulated by the concentration of $H_3O^{+}$ and dissolved $CO_2$ in blood.
$HbO_2 + H_3O^{+} + CO_2 \rightleftharpoons (H^{+} - Hb - CO_2) + O_2 + H_2O$
Release of $O_2$ is favoured when there is:

According to Le Chatelier's principle,if a gaseous mixture is compressed,what will be the effect on the equilibrium of the following reaction: $N_2O_{4(g)} \rightleftharpoons 2NO_{2(g)}$?

For the formation of $NH_{3(g)}$ from $H_{2(g)}$ and $N_{2(g)}$,which one of the following graphs represents the yield of ammonia at equilibrium? (Assume $T_1 < T_2$,unless mentioned)

In a reversible reaction,a catalyst is a substance that .....
