You wish to monitor the progress of a reaction using pressures.Suppose 17.06 g of N2 (28.02 g/mol) and 1.228 g of H2 (2.016 g/mol) are initially present in a 20.0 L reaction vessel at 127
C.Nitrogen and hydrogen can react to form ammonia (17.04 g/mol) according to the reaction shown.At a given point, the total pressure (the sum of the pressures of N2, H2, and NH3 present) is 1.48 atm.What percentage of the initial N2 has reacted?
N2 (g) =3 H2 (g) 2 NH3 (g)
A) 74.0%
B) 26.0%
C) 52.0%
D) 60.9%
E) 15.8%
