Question

What is the change in entropy when 7.61 mL of liquid benzene (C6H6, d = 0.879 g/mL) is combusted in the presence of 22.3 L of oxygen gas, measured at 298 K and 1 atm pressure? (R = 0.0821 L · atm/(K · mol)) 2C6H6(l) + 15O2(g) → 12CO2(g) + 6H2O(l); ΔS° = –437.7 J/K at 298 K

	a.	18.7 J/K
	b.	398 J/K
	c.	436 J/K
	d.	45.3 J/K
	e.	37.4 J/K
