Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs. Hydrogen fluoride must be stored in stainless steel containers, and aqueous solutions must be stored in plastic bottles. Hydrogen fluoride can be produced from H2 and F2:

H2(g) + F2(g) 2 HF(g) Keq = 115
In a particular experiment, 4.65 bar each of H2 and F2 are added to a 3.38 L flask.

A) What is the equilibrium partial pressure of H2?

Units: bar

The number of significant digits is set to 3; the tolerance is +/-5%

B) What is the equilibrium partial pressure of F2?

Units: bar

The number of significant digits is set to 3; the tolerance is +/-5%

C) What is the equilibrium partial pressure of HF?

Units: bar

The number of significant digits is set to 3; the tolerance is +/-5%
