Question

What is defined as a fraction with equilibrium product concentrations in the numerator and equilibrium reactant concentrations in the denominator and each concentration raised to a power equal to the corresponding stoichiometric coefficient in the balanced chemical equation? Select one:

A. Mass action
B. Equilibrium expression
C. Reversibility expression
D. Reaction expression
E. Product quotient

Answer 1

B. Equilibrium expression

Step-by-step explanation:

Imagine this example

aA + bB ⇄ nAB

K = Equilibrium constant.

How do you calculate K

K = (AB)ⁿ / Bᵇ . Aᵃ
