Chemical and Ionic Equilibrium 1 Question 33
34. When $\mathrm{NaNO}{3}
(1986, 1M)
(a) addition of
(b) addition of
(c) increasing temperature favours forward reaction
(d) increasing pressure favours reverse reaction
35 For the gas phase reaction,
$$ \mathrm{C}{2} \mathrm{H}{4}+\mathrm{H}{2} \rightleftharpoons \mathrm{C}{2} \mathrm{H}_{6} \quad(\Delta H=-32.7 \mathrm{kcal}) $$
carried out in a vessel, the equilibrium concentration of $\mathrm{C}{2} \mathrm{H}{4}$ can be increased by
(a) increasing the temperature
(b) decreasing the pressure
(c) removing some
(d) adding some $\mathrm{C}{2} \mathrm{H}{6}$

Solution:
- $\mathrm{NaNO}{3}(s) \rightleftharpoons \mathrm{NaNO}{2}(s)+\frac{1}{2} \mathrm{O}_{2}(g), \Delta H>0$
$\mathrm{NaNO}{3}
