Exam 14: Chemical Equilibrium

At 900.0 K,the equilibrium constant (K_p)for the following reaction is 0.345 bar^-1: $2 \mathrm { SO } _ { 2 }$ + $\mathrm { O } _ { 2 }$ (g)? $2 \mathrm { SO } _ { 3 }$ (g) At equilibrium,the partial pressure of $\mathrm { SO } _ { 2 }$ is 35.0 bar and that of $\mathrm { O } _ { 2 }$ is 15.9 bar.The partial pressure of $\mathrm { SO } _ { 3 }$ is ________ bar.

The reaction below has a K_p value of 3.3 × 10^-5 bar.What is the value of K_c for this reaction at 700 K? $\quad$$\quad$ 2SO₃(g)⇌ 2SO₂(g)+ O₂(g)

Express the equilibrium constant for the following reaction: $\quad$$\quad$$\quad$ SO_2(g) + H₂O(l)? H₂SO₃(aq)

Consider the following reaction,equilibrium concentrations,and equilibrium constant at a particular temperature.Determine the equilibrium concentration of NO₂(g). $\quad$ N₂O₄(g)⇌ 2NO₂(g)K_c = 0.21 M $\quad$ [N₂O₄]_eq = 0.039 mol L^-1
