1. the following reaction is done at stp:

n2 (g) + 3 h2 (g) → 2 nh3 (g)

if 1.5 liters of nitrogen gas are added to an excess of hydrogen gas, how many liters of nh3 gas will form?

a) 0.75 liters
b) 1.5 liters
c) 3.0 liters
d) 4.5 liters

option C. 3L

Explanation:

N2 + 3 H2 → 2 NH3

From the above reaction,

1L of N2 produce 2L of NH3.

Therefore 1.5L of N2 will produce XL of NH3 i.e

XL of NH3 = 1.5 x 2 = 3L
