Question

If you use a different value for the molar absorptivity (s), which of the following variables change or don't change? Explain your answer for each with complete sentences (no more than three). 1. a. Kc b. AH c. AS Write down your calculated value for AH 2. below. Is the reaction endothermic of exothermic? Explain with at least one complete sentence. 3. Write down the values for AHn (in kJ/mol) and AS (in J/K-mol) that you calculated in the lab. Based on these values, calculate the standard state Gibbs free energy (AGn) in kl/mol for the reaction at 298 K. Please show all work.
