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

Answer:

B. Equilibrium expression

Explanation:

Imagine this example

aA  +  bB  ⇄  nAB

K = Equilibrium constant.

How do you calculate K

K = (AB)ⁿ / Bᵇ . Aᵃ
