When $KOH$ is dissolved in water,heat is evolved. If the temperature is raised,the solubility of $KOH$

When a vapor is heated slowly from $25\,^oC$ at atmospheric pressure,its color initially deepens. When the temperature is increased above $160\,^oC$,the color fades. At $600\,^oC$,the vapor becomes almost colorless,but when the pressure is increased at this temperature,the color deepens again. What is this vapor?

Mention the conditions required to maximize the yield of ammonia.

Describe the effect of the following on the equilibrium of the reaction: $2H_{2(g)} + CO_{(g)} \rightleftharpoons CH_3OH_{(g)}$
$(a)$ Addition of $H_2$
$(b)$ Addition of $CH_3OH$
$(c)$ Removal of $CO$
$(d)$ Removal of $CH_3OH$

In a reversible reaction at $300 \ K$,$K_c > K_p$ and $\Delta H = +40 \ kcal$. The product will be obtained in a higher amount on:

When $I_2$ dissociates to its atomic form the following reaction occurs:
$I_{2(g)} \rightleftharpoons 2I_{(g)} ; \Delta_r H^o = +150 \ kJ \ mol^{-1}$
The forward reaction is favoured at:
