Answer the following questions using the chemical reaction and thermochemical information given below:
NH3(g) + HCl(g) ⇌ NH4Cl(s)
ΔHf° (kJ/mol) S° (J mol-1 K-1)
NH4Cl -314.40 94.60
NH3 -45.94 192.77
HCl -92.31 186.90
1).Determine ΔG°rx (in kJ) for this reaction at 306.85 K. Assume ΔH°f and S° do not vary as a function of temperature. Report your answer to two decimal places
2). Determine the equilibrium constant for this reaction at 306.85 K. Report your answer to three significant figures in scientific notation.
3). If the partial pressure of HCl is 6.11 atm and the partial pressure of NH3 is 1.2 atm, determine ΔG (in kJ) for this reaction at 306.85 K. Report your answer to two decimal places in standard notation (i.e. 123.45 kJ)
