IS
The system below was at equilibrium and
then some O2 gas was added to the
container. What change will occur for the
system?
2SO2(g) + O₂(g) = 2SO3(g) + 198 kJ
A. The reaction will shift toward the reactants (left) and
increase the concentrations of SO₂ and O₂.
B. The reaction will shift toward the reactants (left) and
decrease the concentration of SO3.
C. The reaction will shift toward the products (right) and
decrease the concentration of SO2.
D. The reaction will shift toward the products (right) and
increase the concentration of SO2.
Answer:
C
Equilibrium shifts to the right, as more SO₃ are formed, the products are being used up. Hence, the concentration of SO₂ decreases!
I hope this helps!
