KCET 2025 Chemistry Paper

Here's how Le Chatelier's principle applies to
CO(g)+3H2(g)⇌CH4(g)+H2O(g):
Adding a reactant shifts equilibrium toward products.
- Increasing [CO] (option a) drives the forward reaction.
Removing a product also shifts equilibrium toward products.
- Decreasing [CH4] (option c ) removes a product and pulls the reaction to the right.
Options b (adding H2O ) and d (removing H2 ) work against methane formation.
