For the gas phase reaction, PCl g PCl g Cl g Which of the following conditions are correct? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

g H U n RT and G H T S for a spontaneous process, must be negative. 5 3 2 PCl g PCl g Cl g In this reaction, g n = 2 – 1 = 1 Thus, H is positive, i.e., > 0 If is positive, then to maintain the value of G negative, S should be positive, i.e. S 0 ,
