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

The reaction between thiocyanate ion and ferric ion is given below. If $SCN^-$ ions are added to the equilibrium mixture,what will happen? $SCN^-_{(aq)} (\text{colorless}) + Fe^{3+}_{(aq)} (\text{yellow}) \rightleftharpoons [Fe(SCN)]^{2+} (\text{deep red})$

For the equilibrium $2NO_{2(g)} \rightleftharpoons N_2O_{4(g)} + 14.6 \ kcal$,the increase in temperature would

In the manufacture of $NH_3$ in Haber's continuous flow process involving the reaction $N_{2(g)} + 3H_{2(g)} \longleftrightarrow 2NH_{3(g)}$,$\Delta H = -22.08 \ kcal$. The favourable conditions are:

In which of the following reactions will an increase in pressure lead to an increase in the yield of products?

How will an increase in pressure affect the following equilibrium? $C_{(s)} + H_2O_{(g)} \rightleftharpoons CO_{(g)} + H_{2(g)}$
