The balanced chemical equation for the reaction of barium oxide with dioxygen should be given. Concept introduction: A chemical equation consists of reactants and products. The two are separated by an arrow. Each substances of reactants and products are separated from other by a plus sign. The reactants lies on left hand side while products lies on right hand side of the reaction. A balanced chemical equation occurs when the number of atoms in reactant side is equal to the number of atoms in the product side.

Question

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits. 0.035 atm ✓ G 00. 18 Ar
