We have 1 mol of N2 gas that is heated at constant pressure from 300K to 5770K on the surface of the sun.
i) Find H and S given that P for nitrogen is (25.7 + 0.0130T) J/mol-K.
ii) Now, redo your calculation assuming that the second T-dependent term in the P expression is negligible (i.e. P does not depend on T)
iii) What is the percent error if we assume that P is not temperature dependent?
