Exam points
- Explain that forward and reverse reactions continue at the same rate in a sealed system.
- State that reactant and product concentrations stay constant, not equal.
3.20C Characteristics of dynamic equilibrium question 1
[Maximum number: 1]
Methanoic acid also reacts with propanol to form an ester.
The equation for the reaction is
HCOOH+C3H7OH⇌HCOOC3H7+H2O
When this reaction occurs in a sealed container, the reaction can reach dynamic equilibrium.
Give one characteristic of a reaction at dynamic equilibrium.
forward and backward reactions occur at the same rate
Or:
- concentrations of reactants and products remain constant / stay the same / do not change
Allow:
- amounts / moles / ratios of reactants and products remain constant
Reject:
- concentrations of reactants and products are equal / the same
