Question

Which of the following mole ratios is not correct in the reaction below:

N2 + 3 H2 --> 2 NH3

A) mol H2 / 1 mol NH3 3
B) mol H2 / 1 mol N2 3
C) mol N2 / 2 mol NH3 1
D) mol NH3 / 3 mol H2 2

Help

Answer 1

A). 3 mol H2 / 1 mol NH3

Step-by-step explanation:

Mole ratio showcases how two substances involved in a chemical reaction relates in terms of number of moles (mol). The following chemical equation is given:

N2 + 3H2 → 2NH3

According to the above chemical equation;

- 1 mole of N2 is involved

- 3 moles of H2 is involved

- 2 moles of NH3 is involved

Hence, this means that according to the options provided in this question, the incorrect one is 3 mol H2 / 1 mol NH3 because 2 moles rather than 1 mol of NH3 is involved.
