Question

1-The equilibrium constant Kc for the equation 2H2(g) + CO(g) ⇌ CH3OH(g) is 11 at a certain temperature. If there are 2.63 × 10−2 moles of H2 and 7.15 × 10−3 moles of CH3OH at equilibrium in a 6.29−L flask, what is the concentration of CO? ?M

2-In an analysis of the following reaction at 100°C,Br₂(g) + Cl₂(g) ⇌ 2BrCl(g) the equilibrium concentrations of the reactants were found to be [Br₂] = 4.0×10⁻³M and [Cl₂] = 7.7 ×10⁻³M. The equilibrium constant is K_c = 7.1. Determine the value of [BrCl].

3-In an analysis of the following reaction at a certain temperature, Br₂(g) + Cl₂(g) ⇌ 2BrCl(g) the equilibrium concentrations were found to be [Br₂] = 2.4 ×10⁻³M, [Cl₂] = 3.0 ×10⁻²M, and [BrCl] = 1.9 ×10⁻²M. Write the equilibrium expression, and calculate the equilibrium constant for this reaction at this temperature.
