a)
Interpretation:Whether in below reaction mole fraction of reactants or products increases or remains same as volume is increased is to be determined.
Concept introduction: In accordance to Le Chatelier’s principle change in reaction condition brings changes in position of equilibrium and shifts equilibrium in that direction that tends to decrease the change. It states that with increase in pressure of container its volume decreases. Increase in volume shifts equilibrium in that direction that increases the overall volume. Decrease in volumes shifts equilibrium in that direction that has les number of moles.
Mole fraction is the ratio of number of moles of component in mixture to total number of moles in a solution. Hence mole fraction is directly related to number of moles.

- Hi I need help on the question provided in the image.arrow_forwardDraw a reasonable mechanism for the following reaction:arrow_forwardDraw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
