Consider the following reaction at equilibrium. What will happen if O2 is removed from the reaction? 4 FeS2(s) + 11 O2(g) ⇌ 2 Fe2O3(s) + 8 SO2(g)

Consider the following reaction, equilibrium concentrations, and equilibrium constant at a particular temperature. Determine the equilibrium concentration of H2O(g). C2H4(g) + H2O(g) ⇌ C2H5OH(g) Kc = 9.0 × 103 [C2H4]eq = 1.69 M [C2H5OH]eq = 0.015 M  

The isomerization of methylisonitrile to acetonitrile CH3NC(g) → CH3CN(g)is first order in CH3NC. The rate constant for the reaction is 6.99 × 10-4 s-1 at 503 K. The of the reaction when the initial [CH3NC] is 0.030 M is ________ s.

Calculate the pOH of a solution that contains 4.8 × 10-6 M OH⁻ at 25°C.

The equilibrium constant is given for one of the reactions below. Determine the value of the missing equilibrium constant. H2(g) + Br2(g) ⇌ 2 HBr(g) Kc = 3.8 × 104 2 HBr(g) ⇌ H2(g) + Br2(g) Kc = ?
