Question

when the molar concentrations of SO2,O2,SO3 at equilibrium at certain temperature are 0.5,0.25,&0.25M respectively kc for 2SO3->2SO2+O2 is​

Answer 1

Answer:

Here's your answer mate !

Explanation:

Answer 2

Answer:

Molar concentrations for the given compounds are $=1 \mathrm{M}=1 \mathrm{molL}^{-1}$

Explanation:

$2 \mathrm{SO}_{3} \rightleftharpoons 2 \mathrm{SO}_{2}+\mathrm{O}_{2}$

$\text { at } \mathrm{Eqb}^{\mathrm{m}} \quad 0.25 \mathrm{M} \quad 0.5 \mathrm{M} \quad 0.25 \mathrm{M}$

$\mathrm{K}_{\mathrm{C}}=\frac{\left[\mathrm{O}_{2}\right]\left[\mathrm{SO}_{2}\right]^{2}}{\left[\mathrm{SO}_{3}\right]^{2}}$

$\Rightarrow \mathrm{K}_{\mathrm{C}}=\frac{[0.25][0.5]^{2}}{[0.25]^{2}} \frac{\mathrm{M}^{3}}{\mathrm{M}^{2}}$

$\Rightarrow \mathrm{K}_{\mathrm{C}}=1 \mathrm{M}=1 \mathrm{molL}^{-1}$
