4. Ibrahim is learning about the conditions for equilibrium. He understands that temperature can affect the position of equilibrium. According to Le Chatelier's principle, how does an increase in temperature affect an endothermic reaction?
5. Equilibrium constant expression does not include:
6. Which condition favors formation of more products in exothermic reaction?
7. Which factor does NOT affect the position of equilibrium?
8. Removal of products shifts equilibrium toward:
9. Rania is studying the concept of chemical equilibrium. She learns that equilibrium can be disturbed by changing conditions. According to Le Chatelier's principle, what happens when a system at equilibrium is disturbed?
10. Fatima is studying the conditions for equilibrium. She understands that for a reaction to be at equilibrium, the forward and reverse reactions must have the same rate. What happens to the concentrations of reactants and products when the rates are equal?
