.

A student was doing an equilibrium reaction in lab and found that the reactant A had an absorbance value of 0.615. The product had an absorbance value of 0.233, and at equal amounts of reactants and products had an absorbance value of 0.350. Starting at equal amounts of reactants and products, the student then tinkered with the reaction in a variety of ways. Below is a table of their results: Variable Absorbance Value Added more reactant 0.263 Cooled in ice Which of the following is true? 0.541 I. The reaction is exothermic II. The reaction is endothermic III. You cannot determine if the reaction is endo/exothermic Which of the following is the best explanation? a. Increased absorbance = increased products b. Increased absorbance = increased reactants c. Decreased absorbance = increased products d. Decreased absorbance = increased reactants ||| I and b Il and a I and d
