Equilibrium constant for a given reaction is:

Usman is learning about Le Chatelier's principle. He knows that increasing the pressure of a gaseous reaction will shift the equilibrium towards fewer gas molecules. In the reaction: N2 + 3H2 ⇌ 2NH3, what is the effect of increasing pressure?

Increase in pressure favors the side with:

Which change shifts equilibrium to the right?

Le Chatelier’s principle explains the effect of:

Emma is learning about the equilibrium condition. She understands that for equilibrium to be established, the reaction must be reversible. Which of the following is a characteristic of a reversible reaction?

Carlos is learning about chemical equilibrium. He understands that the equilibrium constant (K) depends on temperature. If the temperature of an exothermic reaction is increased, what happens to the value of K?

Samir is learning about reversible reactions. He understands that in a reversible reaction, the reactants are never completely converted to products. Why is this?

Which statement about equilibrium is correct?

Waleed is learning about the conditions for equilibrium. He knows that the reaction must be reversible and the system must be closed. Which of the following is also required for equilibrium?
