DESCRIPTION
137. Solving a chemistry problem
2 moles of N2 and 1 mole of O2, which are at 27 ° C and 1 atm, are mixed. After that, the gas mixture is heated to 827 ° C and compressed to 5 atm. Find the change in the entropy of the system if the average molar heat capacities (Сp) of N2 and 02 are equal to 29.58 and 32.97 J ∙ mol-1 ∙ K-1, respectively.
