1. For the reaction below, _rH = 5005.0 kJ mol¹. What is the standard enthalpy of formation of C₁₀H₈(s)?

C₁₀H₈(s) + 12 O₂(g) 10 CO₂(g) + 4 H₂O(l)

Give your answer in kilojoules per mole (kJ mol¹), accurate to one decimal place

Data

Substance	Standard enthalpy of formation (in kJ mol1)
CO2(g)	393.5
H2O(l)	285.9

The standard enthalpy of formation of C₁₀H₈(s) is _fH = _____ kJ mol¹.

2. For the reaction below, the constant pressure heat of reaction is q_p = 2051 kJ mol¹ at 25 C. What is the constant volume heat of reaction, q_V , at 25 C? Enter your answer in kJ mol¹, rounded to the nearest kilojoule.

10 CO(g) + 21 H₂(g) C₁₀H₂₂(l) + 10 H₂O(l)

The constant volume heat of reaction is q_V = ____ kJ mol¹.

3. Given that the normal boiling point of CH₃CH₂CH(OH)CH₃ is 99 C, which of the following statements about the process below is/are correct? You may choose more than one, or none, of the statements.

CH₃CH₂CH(OH)CH₃(g, 121 C, 1 atm) CH₃CH₂CH(OH)CH₃(l, 84 C, 1 atm)

You may assume that the temperature of the surroundings is constant and also equal to 84 C.

Note: The normal boiling point (T_nbp) is the boiling temperature at 1 atm. The phase change is reversible at the normal boiling point but irreversible if P = 1 atm and T T_nbp.

		a) The entropy of the system increases: S > 0.
		b) The entropy of the surroundings increases: Ssurr > 0.
		c) The entropy of the universe increases: Suniv > 0.
		d) Work is done by the system on the surroundings.
		e) Heat flows from the system into the surroundings.
		f) The entropy change for the system is equal to H / Tvap.
		g) The entropy change for the system is equal to H / Tsurr.
		h) The process is thermodynamically irreversible.
