In which reaction will the point of equilibrium shift to the left when the pressure on the system is increased?
A. \(\mathrm{C}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{~g}) \leftrightarrow \mathrm{CO}_{2}(\mathrm{~g})
B. \(\mathrm{CaCO}_{3}(\mathrm{~s}) \leftrightarrow \mathrm{CaO}(\mathrm{s})+\mathrm{CO}_{2}(\mathrm{~g})\)
C. \(2 \mathrm{Mg}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{~g}) \leftrightarrow\) \(2 \mathrm{MgO}(\mathrm{s})\)
D. \(2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \leftrightarrow 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})\)
Correct Answer: B
