Question

 

Consider the reaction:

H2(g) + Br2(g) --> 2HBr(g)

ΔH˚ = -103.8 kJ/mol

In a particular experiment, equal moles of H2(g) at 1.00atm and Br2(g) at 1.00 atm were mixed in a 1.00 L flask at 25˚C and allowed to reach equilibrium. Then the molecules of H2 at equilibrium were counted using a very sensitive technique and 1.10 x 1013 molecules were found. For this reaction calculate the values of K, ΔG˚, and ΔS˚.
