⦁ Nitrogen reacts with hydrogen according to the following reaction: N2 (g) + 3H2 (g) 2NH3 (g)

If the initial partial pressures of N2 and H2 are 1.2 atm and 0.8 atm, respectively, what is total pressure at the end of the reaction in atm?
Assume the reactions occurs in a 1.0L flask at 298K
R = 0.08206 L*atm/mol*K
