Using an ion-selective electrode, a student measures the concentration of chloride ions in a solution as 0.20 M. The solution also contains either nitrate or sulfate ions. How can the student determine which ion(s) is present in the solution and calculate their concentration?

A chemistry student needs to determine how the equilibrium concentration of products and reactants change when the temperature is increased in the reaction: 2 SO2 (g) + O2 (g) ⇌ 2 SO3 (g) Given the initial concentrations of 0.15 M SO2, 0.025 M O2, and 0 M SO3, and a temperature increase of 50°C, calculate the new equilibrium concentration of each compound using Le Chatelier's Principle.
