Question

Part D Please !!!

Consider the following reaction occurring at 298 K:
BaCO3 (s) = BaO (s) + CO2 (g)
Part A
Show that the reaction is not spontaneous under standard conditions by calculating A,G°.
Express your answer using one decimal place.
A,G° = 219.7 kJ mol-1
%3D
Previous Answers
Correct
Correct answer is shown. Your answer 219.6 kJ mol-1 was either rounded differently or used a different number of significant figures
than required for this part.
Part B
If BaCO3 is placed in an evacuated flask, what partial pressure of CO2 will be present when the reaction reaches equilibrium?
Express your answer using three significant figures.
