2) The following adsorption isotherm data were taken for the adsorption of SO? on activated charcoal at 273 K. In addition, separate experiments, conducted at a constant pressure of 180 mm Hg and at temperatures of 302 K and 351 K, gave the following results for the quantity of SO? adsorbed on the charcoal: 0.25 g/g at 302 K and 0.10 g/g at 351 K P [mm Hg] C502 [g/g adsorbent] 73 0.214 180 0.471 309 0.726 540 1.089 882 1.494 a) Determine the Langmuir isotherm parameters at 273 K b) Determine the Freundlich isotherm parameters at 273 K c) The Langmuir isotherm can be written in the following form $\frac{C_A}{C_S} = \frac{K_A P_a}{1 + K_A P_a}$ The temperature dependency of K? is often written as $K_A = A_0 exp(\frac{-E}{RT})$ Test this assertion. Determine A? and E A? = E = m³ atm/mol

Ammeter with Internal Resistance Using MS Excel (or a similar program) plot $V_s$ versus $i_m$ and add a linear trendline along with the equation of the line to linearize the data. Use the snipping tool to include a picture of the data, plot, and trendline and include it below. Based on equation (1) and the value of the slope of the trendline, calculate the value of the internal resistance of the ammeter, $R_{int}$. Is this internal resistance relatively low? Pay particular attention to the units and order of magnitude. How does the internal resistance of the ammeter compare to the value of the resistor $R$ in the circuit?

4. A cam with a minimum radius of 20 mm is rotating clockwise with a uniform speed of 200 rpm. The cam is to be designed to give a knife edge follower at the end of a valve rod the described motion: 1. Raise the valve through 40 mm during 120° rotation of the cam 2. Keep the valve fully open through the next 90° 3. Lower the valve during the next 60° and, 4. Keep the valve closed during rest of the revolution The displacement of the valve while being raised and lowered undergoes a simple harmonic motion. a) Draw the displacement diagram for one complete revolution of the cam (use a scale of 10 mm : 20°). b) Draw the cam profile.
