equilibrium

This symbol indicates that a reaction is _____

• reversible

• irreversible

Around what time does the reaction reach equilibrium?

• 25 min

• 70 min

• 45 min

• 80 min

What are the two factors that help determine that equilibrium is reached?

• Forward reaction rate is faster than the reverse and the concentrations are equal

• Forward and reverse reaction rates are equal and concentrations are equal

• Forward and reverse reaction rates are equal and concentrations are constant

When the rate of the forward reaction is equal to the rate of the backward reaction, the system is said to be in _____

• Chemical Balance

• Chemical Constant

• Chemical Reaction

• Chemical Equilibrium

Which of the two graphs reaches equilibrium?

• Neither

• The left

• Both

• The right

Which of the following is NOT true at equilibrium?

• The concentrations of reactants and products do not change.

• The forward and reverse reactions proceed at the same rate.

• The concentration of the reactants is equal to the concentration of the products.

• The forward and reverse reactions continue to occur.

When the rate of the forward reaction is equal to the rate of backward reaction, the system is said to be in

• Chemical Equilibrium
• Chemical Balance
• Chemical Constant
• Chemical Reaction

Such reactions which continue in both directions are called:

• Irreversible reactions

• Reversible reactions

• Non-reactive reactions

• dynamic reactions

A complete reaction is in which:

• All the reactants convert into products

• All the reactants do not convert into products

• Half reactants convert into products

• only 10% reactants convert into products

Changes in pressure will only affect substances that are in the __________ state.

• gaseous
• liquid
• solid
• plasma
