(1) Find the limiting reactant
MM of I2 = 253.8 g/mol
MM of F2 = 38.0 g/mol
mol IF5 = 0.0804 mol IF5
mol IF5 = 0.1074 mol IF5
Gaseous iodine pentafluoride, IF5, can be prepared by the reaction of solid iodine and gaseous fluorine:
I2 (s) + 5 F2(g) → 2 IF5 (g)
A 5.10-L flask containing 10.2 g I2 is charged with 10.2 g F2, and the reaction proceeds until one of the reagents is completely consumed. After the reaction is complete, the temperature in the flask is 125oC.
What is the partial pressure of IF5 in the flask?
