Question

Consider the following equilibrium: 2NO(g) + C1, (g) = 2NOCI(g) AG"=-41. kJ Now suppose a reaction vessel is filled with 0.628 atm of chlorine (C12) and 3.94 atm of nitrosyl chloride (NOCI) at 170. °C. Answer the following questions about this system: Under these conditions, will the pressure of Cl, tend to rise or fall? Orise fall Х ? O yes Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of Cl, will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of Cl, will tend to fall, can that be changed to a tendency to rise by adding NO? O 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.

Answer 1

1. Pressure of chlorine will fall.since K equilibrium is a positive number so the reaction will proceed in forward direction forming more of NoCl and chlorine will reduce so its pressure will reduce.

2.yes possible to reverse the tendency by adding a NO
