Question description

At a particular temperature, K = 1.00×102 for the reaction:

H2(g) + F2(g)> 2HF(g)

2 and 1.90 mol of F2 are introduced into a 1.25-L flask and allowed to react. At equilibrium, all species remain in the gas phase.

Q.1)What is the equilibrium concentration (in mol/L) of H2?

2.53×10-1 mol/L

Q.2) To the mixture above , an additional 9.50×10^-1 mol of H2 is added. What is the new equilibrium concentration (in mol / L ) OF HF

Strictly need in 15-20 mins
