surface Area

Question 15

know phase diagrams

Answer 15

look up

Question 16

Le chatelier’s principle : increased pressure causes what change to volume and which shift in the direction of the reaction

Answer 16

decreased volume, favors direction with the lowest total number of compressible moles of gas

Question 17

Le chatelier’s principle : decreased pressure causes what change to volume and which shift in the direction of the reaction

Answer 17

increased volume, favors reaction side with the lowest density ( higher number of moles)
