Question

Using reaction free energy to predict equilibrium compo.. Consider the following equilibrium Now suppose a reaction vessel is filled with 4.87 atm of ammonia (NH,) and 4.95 atm of nitrogen (N2) at 623. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of N2 tend to rise or fall? fall ts it possible to reverse this tendency by adding H2 n other words, if you said the pressure of N2 will tend to rise, can that be changed to a tendency to fal by adding H2? Similarly, if you said the pressure of N, will tend to fall, can that be changed to a tendency to rise yes by adding H2 If you said the tendency can be reversed in the second question, calculate the minimum pressure of H2 needed to reverse it. Round your answer to 2 significant digits.

Explanation / Answer

Yes , there is rise in the pressure of N2. Also there is reversion of this condition of we further add H2.
