The thermochemical equation for the formation of 1 mol of copper(II) chloride from its elements, including the energy term, can be written as:
Cu(s) + Cl2(g) → CuCl2(s) + 220.1 kJ
To write a thermochemical equation that includes an energy term within the equation, we need to follow certain steps:
Step 1: Identify the balanced chemical equation for the formation of 1 mol of copper(II) chloride from its elements. Copper(II) chloride is formed by the reaction between copper and chlorine.
Copper + Chlorine → Copper(II) chloride
Step 2: Determine the stoichiometric coefficients for each reactant and product in the balanced equation. In this case, since we are considering the formation of 1 mol of copper(II) chloride, the balanced equation becomes:
Cu(s) + Cl2(g) → CuCl2(s)
Step 3: Include the energy term within the equation. The given information states that the formation of 1 mol of copper(II) chloride releases 220.1 kJ of energy. When energy is released in a chemical reaction, it is represented as a reactant with a negative sign.
Cu(s) + Cl2(g) + 220.1 kJ → CuCl2(s)
This equation indicates that the formation of 1 mol of copper(II) chloride from its elements releases 220.1 kJ of energy.
