Question

Consider the reaction:

2NO2(g) -->N2O4(G)

Throughout the problem you can assume that delta H and delta S are independent of temperature.


A.

Calculate delta H, delta S, and Delta G for this reaction at 30C


B.

Explain, qaulitatively, why the sign of delta S makes sense.


C.

Is this process spontaneous at 30 C? (please include why, not just yes or no)


D.

At what temperature will the sign of delta G change?






Note: I have the answers, I just can't figure out how to geto them


The answer to A is delta H= -57.2 KJ, delta S= -0.755 kj/k, delta G= -4.9 KJ


The answer to B involves fewer mols of gas.


The answer to C is yes, it is spontaneous.


The answer to D is 326 K





Explanation / Answer

The answer to A is delta H= -57.2 KJ, delta S= -0.755 kj/k, delta G= -4.9 KJ
