Problem: 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 125 oC.What is the total mass of reactants and products in the flask?

FREE Expert Solution

Calculate how much product each of the reactants can produce. The reactant that produces the smaller amount of product is the limiting reactant and will be totally consumed.

Given: 

10.2 g I2(s) 
10.2 g F2(g)
Reaction: I2(s) + 5 F2(g)  2 IF5(g)
