Question

O ENTROPY AND FREE ENERGY Using reaction free energy to predict equilibrium compo... L Consider the following equilibrium: N,0, (@)2NO, (e) AG=5.4 kJ Now suppose a reaction vessel is filled with 9.53 atm of dinitrogen tetroxide (N,O,) at 247, °C. Answer the following questions about this system: rise Under these conditions, will the pressure of N2O4 tend to rise or fall? O fall Is it possible to reverse this tendency by adding NO2 X In other words, if you said the pressure of N,0 will tend to rise, can that yes be changed to a tendency to fall by adding NO2? Similar if you said the no pressure of N204 will tend to fall, can that be changed to a tendency to rise by adding N0, If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO2 needed to reverse it. Round your answer to 2 significant digits

Answer 1

According to le chatelier principle the pressure of N2O4 tends to fall down to forward the reaction.

And minimum pressure is calculated in the image provided.
