Question

Which of the following can we predict from an equilibrium constant for a reaction?

1. the extent of a reaction

2. which direction a reaction will proceed by measuring the concentrations of reactants and products

3. whether a system is at equilibrium by measuring the concentrations of the reactants and products.


A) 1 only
B) 2 only
C) 3 only
D) 1 and 2 only
E) 1,2 and 3.

Answer 1

Solution:
Equilibrium constant for a reaction predict:
the extent of a reaction;
which direction a reaction will proceed by measuring the concentrations of reactants and
products;
whether a system is at equilibrium by measuring the concentrations of the reactants and products;
So correct answer is E) 1,2 and 3.
Answer: E) 1,2 and 3.
