Consider the reaction H2(g) + I2(g) <=> 2HI(g). What is the effect of increasing the pressure on this equilibrium?

Here's a step-by-step solution to the questions:

QUESTION 1

a) Part 1.1:
The balanced chemical equation is $\text{H}_2\text{(g)} + \text{I}_2\text{(g)} \rightleftharpoons 2\text{HI(g)}$.
To determine the effect of pressure on equilibrium, we compare the total number of moles of gaseous reactants and products.

• Moles of gaseous reactants = $1 \text{ mol H}_2 + 1 \text{ mol I}_2 = 2 \text{ mol}$
• Moles of gaseous products = $2 mol HI = 2 \
