Reaction:            Cl2(g) + 3F2(g) → 2ClF3(g)

Calculate moles of each reactant:

• limiting reactant  forms less amount of product  determines max. amount of product

Ideal gas equation:

nCl2 = 0.0363 mol Cl2

nF2 = 0.0844 mol F2

Mole to mole comparison:

• 1 mol of Cl2 forms 2 moles ClF3

0.0726 mol

###### Problem Details

Chlorine gas reacts with fluorine gas to form chlorine trifluoride.

Cl2(g) + 3F2(g) → 2ClF3(g)

A 2.00 L reaction vessel, initially at 298 K, contains chlorine gas at a partial pressure of 337 mmHg and fluorine gas at a partial pressure of 784 mmHg .

a. What is the pressure of ClF3 in the reaction vessel after the reaction?
b. What is the total pressure in the reaction vessel after the reaction?
