Answer

Answer:

A. adding heat to the product mixture

Explanation:

Step1: Recall Le - Chatelier's principle

Le - Chatelier's principle states that a system at equilibrium will respond to a stress to counteract that stress.

Step2: Analyze heat addition

If heat is added to the product mixture, the system will try to consume the added heat. For an exothermic reaction (assuming this reaction is exothermic as no heat information is given but common sense in such reactions), adding heat to products will shift the equilibrium to the left to absorb the extra heat.

Step3: Analyze other options

  • Option B: A faster forward - reaction rate initially moves the system towards the products, not left.
  • Option C: Increased collisions between CO and H₂ increase the forward - reaction rate and shift equilibrium to the right.
  • Option D: The escape of water from the mixture shifts the equilibrium to the right to replace the lost water.
  • Option E: Placing the mixture in a cold - water bath (removing heat) for an exothermic reaction shifts the equilibrium to the right to produce more heat.
