Worked Solution & Example Answer:A particular reaction is carried out using equal amounts of CH₄(g) and H₂O(g) - VCE - SSCE Chemistry - Question 1 - 2008 - Paper 1
Step 1
Volume of reaction vessel: increased, Temperature: increased
Answer
Increasing both the volume of the reaction vessel and the temperature will lead to the greatest increase in the conversion of reactants to products in this case.
-
Increasing the volume of the reaction vessel decreases the concentration of the gaseous reactants (CH₄ and H₂O), thereby shifting the equilibrium position towards the products according to Le Chatelier's principle.
-
Increasing the temperature generally favors the endothermic reaction direction, resulting in more products formed, again shifting the equilibrium to the right.
Thus, option A is the most effective choice.
