Chemistry - Chemical Equilibrium Question with Solution | TestHub

Consider the following reaction:
${\mathrm{N}}_2{\mathrm{O}}_4\left(g\right)=2{\mathrm{NO}}_2\left(\mathrm{g}\right): \Delta {\mathrm{H}}^0=+58\mathrm{k}$
For each of the following cases $(\mathrm{a}, \mathrm{b})$, the direction in which the equilibrium shifts is:
(a) Temperature is decreased.
(b) Pressure is increased by adding ${\mathrm{N}}_2$ at constant T.
