Please calculate the FREEZING point of A in Celsius using the data below, please show all work thank you!!:)
**Problem 2: Calculate the Freezing Point of A** To calculate the freezing point of substance A, in degrees Celsius (°C), use the following thermodynamic data: | Phase of A | ΔH_f (KJ/mole) | S (J/mole K) | |------------|---------------|--------------| | A(s) | -25.3 | 10.8 | | A(l) | +10.5 | 20.4 | | A(g) | -13.8 | 43.8 | - **A(s):** Solid phase of A. - **A(l):** Liquid phase of A. - **A(g):** Gaseous phase of A. - **ΔH_f:** Enthalpy change (in KJ/mole). - **S:** Entropy (in J/mole K). These values provide the necessary enthalpy and entropy changes to determine the freezing point using thermodynamic equations.
