Question

20. Given the reaction at equilibrium:

2 502(8) + O2(g) + 2 SO,(8)
+
As the pressure is increased at constant temperature, the
number of moles of S03(g) produced will
1) decrease
3) remain the same
2) increase

Answer 1

PV = nRT

If pressure increases, so will moles.

The answer is 2) Increase.
