Question

In masteringchemistry, Using relative enthalpy and entropy values, determine how the process is affected after each of the following temperature or pressure changes? Consider that a more effective reaction produces more product or more product in a shorter amount of time. There are 4 questions, 1) Pressure increases by decreasing the container size 2) Temperature decreases while maintaining the container size 3) Temperature increases while maintaining the container size 4) Pressure decreases by increasing the container size They need to be separated More effective, Less effective, Equally effective. I have no idea about this. Please explain it to me and give a correct answer :) Have a good day !

Explanation / Answer

more - temp dec./press increase less- temp incre/press decrease Think about the mols of gas on each side. As the pressure increases it will seek a new eq. on the side with the least number of mols. In this case this will be the products side so more products are formed and thus is was more effective. The temperture affects it becasue it is exothermic and if you decrease the temp you are removing heat, and so the new eq. will be towards the products as A->B+q is for exothermic processes and removing so q (heat) will force the reaction to shift from l to r.
