Question

The equation for the reaction is: N2(g) + 3H2(g) = 2NH3(g)

The forward reaction is exothermic.
Calculate the volume of ammonia produced from the complete reaction of 825dm3 of hydrogen

Answer 1

Answer: 550 dm^3

Step-by-step explanation:

825 Dm3 X 2 moles NH3/ 3 Moles H2

Answer 2

550dm3

Step-by-step explanation:

To calculate the volume of ammonia produced from the complete reaction of 825dm3 of hydrogen, we can use the molar ratio between them, which is 3:2

H2 : NH3

3 : 2

825dm3 of hydrogen was produced, so we will put the unknown volume of ammonia produced as x:

H2 : NH3

3 : 2

825 : x

Cross multiply and equate to each other:

825 × 2 = 3 × x

Simplify even further:

1650 = 3x

Divide by 3 on both sides to work out x:

1650 ÷ 3 = 550dm3

Hence the volume of ammonia produced from the complete reaction of 825dm3 of hydrogen is 550dm3
