Calculate the equilibrium concentrations of reactants and products for the following reaction at a temperature of 25°C and a pressure of 1 atm:2 NO(g) + Br2(g) ⇌ 2 NOBr(g)Given the initial concentrations are [NO] = 0.20 M, [Br2] = 0.35 M, and [NOBr] = 0.015 M. The equilibrium constant (Kc) for the reaction is 4.8 x 10^2 at 25°C.

A chemistry student wants to know how the concentration of reactants and products affects the equilibrium constant of a chemical reaction. They decide to investigate the reaction between nitrogen gas and oxygen gas to form nitrogen dioxide gas, and the equilibrium constant Kc for this reaction. What is the relationship between the concentration of reactants and products and the equilibrium constant for this reaction, and how can this be explained by Le Chatelier's principle?
