The yield of the products in the reaction,$A_{2(g)} + 2B_{(g)} \rightleftharpoons C_{(g)} + Q \ kJ$ would be higher at

Explain the effect of a catalyst on chemical equilibrium with examples.

The gaseous reaction $A(g) + B(g) \rightleftharpoons 2C(g) + D(g) + Q$ is most favoured at

On the basis of the $Le \ Chatelier$ principle,explain how temperature and pressure can be adjusted to increase the yield of ammonia in the following reaction: $N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$; $\Delta H = -92.38 \ kJ \ mol^{-1}$. What will be the effect of the addition of argon to the above reaction mixture at constant volume?

Consider the reaction $HCN_{(aq)} \Leftrightarrow H_{(aq)}^{+} + CN_{(aq)}^{-}$. At equilibrium,the addition of $CN_{(aq)}^{-}$ would

For the reaction $Br_2 \rightleftharpoons 2Br$,the equilibrium constants at $500 \, K$ and $700 \, K$ are $1 \times 10^{-10}$ and $1 \times 10^{-5}$ respectively. The reaction is .......
