🤓 Based on our data, we think this question is relevant for Professor Delgado's class at FIU.

Solution: Using the data in the table, calculate the standard entropy changes (J/mol•K) for the following reactions at 25 °C.S(s) + O2(g) → SO2(g)MgCO3(s) → MgO(s) + CO2(g)2 C2H6(g) + 7O2(g) → 4 CO2(g) + 6 H2O(l)

Problem

Using the data in the table, calculate the standard entropy changes (J/mol•K) for the following reactions at 25 °C.

S(s) + O2(g) → SO2(g)

MgCO3(s) → MgO(s) + CO2(g)

2 C2H6(g) + 7O2(g) → 4 CO2(g) + 6 H2O(l)
