Question

4 - chemical systems and equilibrium (part 1)
k/u - true or false
question 6 (1 point)
at equilibrium, the concentrations of reactants and products remain constant because the forward and reverse reaction rates are equal.
true
false
question 7 (1 point)
increasing the temperature of an endothermic reaction will shift the equilibrium position toward the products.
true
false

Explanation:

Question 6

In chemical equilibrium, the forward and reverse reaction rates become equal. This means the amount of reactants converted to products is the same as products converted to reactants, so concentrations of reactants and products remain constant. So the statement is true.

For an endothermic reaction, heat is a reactant. Increasing temperature (adding heat) will cause the equilibrium to shift in the direction that absorbs the added heat, which is the forward direction (toward products) to consume the extra heat. So the statement is true.

Answer:

True
