Nội dung tóm tắt
The scholarly document consists of a set of exercises on chemical equilibrium. The first exercise is focused on calculating the equilibrium constant (K) for a reaction between sodium hydrogen carbonate (NaHCO3) and carbon dioxide (CO2). To solve this problem, the document provides steps to write the balanced equation, determine initial concentrations of reactants and products, and use the equilibrium constant expression. Given initial concentrations of NaHCO3 and CO2 are 0.200 M and 0.100 M respectively, at a temperature of 100°C, the value of K is calculated as approximately 4.00. The remaining exercises in the document involve similar calculations and problem-solving related to chemical reactions and equilibrium.
