A gas occupying a volume of 248 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume.
We had to do an experiment that depolymerized PET into terephthalic acid and ethylene glycol using 1-pentanol and KOH. One of the post-lab questions is as follows:
If you wished to prepare t-butyl propyl ether by a Williamson Synthesis, there are two possible combinations of materials you could choose as alternatives.
The reaction will be spontaneous at high temperatures because increasing the temperature of a system with a negative change in S eventually results in a positive change in G.
