Questions & Step-by-Step Solutions

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what will happen if the temperature is decreased?
  • Step 1: Identify the reaction: CO(g) + 2H2(g) ⇌ CH3OH(g).
  • Step 2: Determine if the reaction is exothermic or endothermic. (Exothermic means it releases heat, endothermic means it absorbs heat.)
  • Step 3: If the reaction is exothermic, understand that heat can be considered a product of the reaction.
  • Step 4: When the temperature is decreased, it is like removing heat from the system.
  • Step 5: According to Le Chatelier's principle, the system will try to counteract this change by producing more heat.
  • Step 6: To produce more heat, the equilibrium will shift to the right, favoring the formation of more products (CH3OH).
