Question

3. Nitrogen dioxide dimerizes according to the following reaction: K-6.7 A 2.25-L container contains 0.055 mol of NO2 and 0.082 mol of N 0s at 298 K. Is the reaction at equilibrium? If not, in what direction will the reaction proceed? 4. Consider the following reaction: NHaHS(s) NH3(g) + H2S(g) At a certain temperature, Kc 8.5 x 103. A reaction mixture at this temperature containing solid NH4HS has [NHa] 0.166 M and [H2S 0.166 M. Will more of the solid form or will some of the existing solid decompose as equilibrium is reached? 5. Consider the following reaction: A reaction mixture is made containing an initial [SO Ch] of 2.3x102 M At equilibrium, [Cl2] 1.3x102 M. Calculate the value of the equilibrium constant.
