C$_3$H$_8$ (g) + 5 O$_2$ (g) → 3 CO$_2$ (g) + 4 H$_2$O (l) The standard enthalpies of formation of CO$_2$ (g) and H$_2$O (l) are - 4.00 x 10$^2$ kJ/mol and - 2.90 x 10$^2$ kJ/mol, respectively. When 11.2 L CO$_2$ (g) at STP is formed via the given reaction, 350 kJ of heat is released. Which of the following statements is/are false for this reaction? I. The standard enthalpy of formation of C$_3$H$_8$ (g) is - 260 kJ/mol. II. 232 kJ of heat is released when 14.4 g H$_2$O (l) is formed via the given equation. III. When this reaction is carried out at constant pressure and temperature, work is done by the reacting system on the surroundings.

2. A piston/cylinder arrangement, shown in Figure 2, contains air at 250 kPa and \( 300^{\circ} \mathrm{C} \). The \( 50-\mathrm{kg} \) piston has a diameter of 0.1 m and initially pushes against the stops. The atmosphere is at 100 kPa and \( 20^{\circ} \mathrm{C} \). The cylinder now cools as heat is transferred to the ambient surroundings. (a). At what temperature does the piston begin to move down? (b). How far has the piston dropped when the temperature reaches ambient? (c). Show the process in a \( \mathrm{P}-\mathrm{v} \) and a \( \mathrm{T}-\mathrm{v} \) diagram.

A 5 kg block is sliding on a horizontal surface while being pulled by a child using a rope attached to the center of the block. The rope exerts a constant force of 27.31 N at an angle of \( \theta=30 \) degrees above the horizontal on the block. Friction exists between the block and supporting surface ( with \( \mu_{s,}=0.24 \) and \( \mu_{k}=0.16 \) ). What is the horizontal acceleration of the block?

Future prices of a stock are modeled with a 1-period binomial tree based on forward prices, the period being 3 months. (i) The stock price is 25 (ii) The strike price Is 26 (iii) The continuously compounded risk-free interest rate is 5%. (iv) The stock pays continuous dividends at a rate of 3%. (v) σ = 0.2. A European call option on the stock expiring in 3 months has a strike price of 26. Determine the number of shares in the replicating portfolio for the call option and the price of the call option
