Consider the following equilibrium: 2NO(g) + Cl₂ (g) 2NOCI (g) AG=-41. kJ Now suppose a reaction vessel is filled with 1.55 atm of chlorine (C1₂). about this system: T Under these conditions, will the pressure of NOCI tend to rise or fall? Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOC1 will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it.
