Question

question 1 (5 points)
chemical equilibrium means an equal amount of reactants and products
a) true
b) false
question 2 (5 points)
q is always equal to k
a) true
b) false
question 3 (5 points)
temperature does not affect a chemical reactions equilibrium

Explanation:

• Question 1: Chemical equilibrium is a state where the rate of the forward reaction equals the rate of the reverse reaction. It does not mean an equal amount of reactants and products. So the statement is false.
• Question 2: \(Q\) (reaction quotient) is equal to \(K\) (equilibrium constant) only at equilibrium. At other times (non - equilibrium conditions), \(Q

eq K\). So the statement is false.

• Question 3: According to Le Chatelier's principle, temperature affects chemical equilibrium. For an exothermic reaction (\(\Delta H<0\)), increasing temperature shifts the equilibrium towards the reactants, and for an endothermic reaction (\(\Delta H > 0\)), increasing temperature shifts the equilibrium towards the products. So the statement is false.

Answer:

• Question 1: B. False
• Question 2: B. False
• Question 3: B. False
