First part of the review of chemical equilibrium. We will discuss how to achieve chemical equilibrium and its consequences, how to mathematically express equilibrium through the equilibrium constant Kc and also what this constant is for. Exercises Solved in this Class 04:41 (UNICAMP 2017) A chemical equation is a mathematical equation in the sense that it represents an equality: all atoms and their quantities that appear in the reactants must also appear in the products. Considering a chemical equation and its corresponding equilibrium constant, it can be correctly stated that, multiplying all its coefficients by 2, the equilibrium constant associated with this new equation will be a. twice the constant of the first chemical equation, which is in accordance with a product. b. the square of the constant of the first equation, which is in accordance with a product. c. equal to that of the first equation, since it is a constant, which is in accordance with a sum. d. the constant of the first equation multiplied by ln 2, which agrees with a sum. 09:32 (FUVEST) N2O4 and NO2, air pollutant gases, are in equilibrium, as indicated: In an experiment, under ambient conditions, 1.50 mol of N2O4 was introduced into a 2.0 liter reactor. Once equilibrium was established, the concentration of NO2 was 0.060 mol/L. What is the value of the Kc constant, in terms of concentration, of this equilibrium?
