1. Complete and Balance the following redox equation. MnO4 + H +Br-->Mn2 +Br2 +H2O (acidic Solution). The sum of the smallest whole number coefficients is
2. Consider the reaction:
SO2(g) + NO2(g) ? SO3(g) + NO(g); K = 12.00?T
The reaction vessel is charged initially with SO3(g) and NO(g), each at a partial pressure of 0.500 atm. In the space below, enter the equilibrium the partial pressure of SO2(g) in units of atm
The equilibrium constant, Kp, for the following reaction is 0.497 at 500 K: PCl5(g) PCl3(g) + Cl2(g) Calculate the equilibrium partial pressures of all species when PCl5(g)
