alleryStart learning →The constant value of the reaction quotient shown by a system at equilibrium is called the:
AEquilibrium constant
BThe rate constant
CThe gas law constant
DAvogadro's constant
Answer & Solution
Correct answer: A. Equilibrium constant
1. The numerical value of the reaction quotient varies as a reaction proceeds towards equilibrium.
2. Once equilibrium is reached it stops changing.
3. The constant value of the reaction quotient exhibited by a system at equilibrium is called the equilibrium constant, K.
4. A rate constant belongs to kinetics rather than to equilibrium.
