Question

what volume of nitrogen at 215 degrees celsius and 715mm Hg would be required to react with 0.100 mol of hydrogen to produce ammonia? N2(g) + 3H2(g)-->2NH3(g)? Any help is greatly appreciated.

Answer 1

0.1 mole H2 will require how many moles N2 at STP? That will be 0.1 mol H2 x (1 mole N2/3 moles H2) = 0.1 mol x (1/3) = ?moles N2. What volume is that. ?mol x 22.4L/mol = ?L H2. Now convert that to the conditions listed with PV = nRT.
