Chemical Equilibrium and Reactions

What is the scientific term for a state of balance in a system?

• Stability

• Equilibrium

• Harmony

• Stasis

In chemistry, what is the process called when reactants combine to form products?

• Reverse reaction

• Balanced reaction

• Forward reaction

• Complete reaction

What happens in a reverse chemical reaction?

• Reactants are created from new substances.

• Products change back into reactants.

• The reaction stops completely.

• Energy is always released.

What defines a chemical equilibrium state?

• When all reactants have been completely used up.

• When the forward and reverse reactions occur at the same rate.

• When the reaction stops and no more products are formed.

• When only products are present in the system.

What was a significant positive impact of the Haber process?

• It led to the invention of new types of weapons.

• It made chemical fertilizers possible, improving agriculture.

• It caused a major explosion in a laboratory.

• It helped scientists understand equilibrium better.

If a chemical reaction at equilibrium produces a product, and that product is continuously removed, what happens to the reaction?

• The reaction stops completely.

• The reaction shifts to produce more of the product.

• The reaction shifts to produce more of the reactants.

• The temperature of the reaction increases.

For a reaction where 4 moles of gas react to form 2 moles of gas, what would happen if the pressure is increased?

• The reaction would shift to produce more reactants.

• The reaction would shift to produce more products.

• The reaction would stop.

• The temperature would decrease.

If a chemical reaction is endothermic, meaning it consumes heat, how can you favor the production of more products?

• By decreasing the temperature.

• By increasing the temperature.

• By adding a catalyst.

• By decreasing the pressure.
