1. If the delta G'° of the reaction A --> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from A to B. - E For the reaction A --->B, delta G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of 2 mmol of B, 8 mmol of A. Which is the most li...

Experiment #: 7 Title: Organic Synthesis Purpose: The purpose of this lab was to determine the process of synthesizing various carboncontaining organic products including aspirin, urea, & salicylic acid. In doing so, we were also able to calculate the percent yield in each of these experiments. Procedure: Part 1: Synthesis of aspirin 1. Placed 2.0 g of salicylic acid & placed it in a flask 2. 5.0 mL of acetic anhydride was then added to the flask & mixed 3. 5 drops of sulfuric acid was a...
