Please help with these 1. Calculate ΔG (in kJ) at 298 K for some solid ZnF2, 0.082 M Zn2+ and 0.039 M F-(aq). 2.Calculate the equilibrium constant at 45 K for a reaction with ΔHrxno = 10 kJ and ΔSrxno = -100 J/K. (Don't round unil the end. Using the exponent enlarges any round-off error. Calculate the equilibrium constant at 136 K for the thermodynamic data in the previous question. ( Problem 2)
