For , increasing the pressure shifts the equilibrium
Answer and explanation
Correct answer: A. to the right
- Step 1: Count the stoichiometric moles of gaseous reactants and products: has on the left and on the right.
- Step 2: Apply Le Chatelier's principle: increasing total pressure drives the system in the direction that reduces the total number of gas moles.
- Step 3: Since the product side contains fewer gas moles (), the equilibrium position shifts to the right.
Answer
to the right.
Why not the others: The alternative options (in no direction, to the left, to the left and then right) correspond to incorrect stoichiometric ratios, wrong reaction intermediates, or arithmetic evaluation errors.
