Part C Assume that the partial pressure of sulfur dioxide, Pso₂, is equal to the partial pressure of dihydrogen sulfide, PH₂S, and therefore Pso₂ = PH₂S. If the vapor pressure of water is 21 torr, calculate the equilibrium partial pressure of SO2 (Pso₂) in the system at 298 K. Express the pressure in atmospheres to two significant figures.

Correct
Since both the temperature T and the standard free-energy change, AGO, are provided to three significant
figures, after substituting values for known variables the equation AG° = −RT ln(K₂) simplifies to
In(K₂)
=
<
36.6, where 36.6 is known to three significant figures. When you raise a value to the power of e, only
the digits after the decimal point are used to determine the number of significant figures in the answer. Therefore,
