C. Answer the following questions about this system: fa Under these conditions, will the pressure of NOCI tend to rise or fall? Is t possible to reverse this tendency by adding NO? In other words, r you said the pressure of NOCI wil tend to rise, can that be changed to a tendency to taa by adding NO? Similarly, ir you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? in the second question, calculate If you said the tendency can be reversed the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits. Explanation Check

Explanation / Answer

Under these conditions, will the pressure of NOCl tend to rise or fall?

Rise-------------answer

tempted to think that the forward reaction is spontaneous,

will tend to fall,as ---- the standard reaction free energy is negative.

==========================================

Is it possible to reverse this tendency by adding NO? YES---------answer

--================================================================

In other words, if you said the pressure of NOCl will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCl will tend to fall, can that be changed to a tendency to rise by addingNO?         No -------answer

--================================================================

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.

= 0.28 atm-answer
