1. a. Henry's law states that at a constant temperature, the amount of dissolved gas is directly proportional to the partial pressure of its gas phase. Using your knowledge on Henry's law constant, you are required to formulate the production of carbonated drinks. i. Suggest the amount of CO2 gas that needs to be dissolved in water to produce 320 mL of carbonated canned drink at 557 kPa. Express the dissolved CO2 in ppm, and molality assuming the density of solution is 1034 kg/m. ii. During the packaging process, elaborate the required conditions to increase the dissolved amount of CO2. Provide a calculation to show the effect of the proposed conditions on the amount of gas dissolved in the liquid and determine when the equilibrium is eventually reached. iii. Explain the fizziness of the carbonated drink when the can is opened. [20 marks) As a chemist in one of the top chemical companies in Malaysia, you are required to evaluate the decomposition of dinitrogen pentoxide at b. 333 K. The decomposition reaction can be monitored by measuring the concentration of dinitrogen pentoxide at every 6-minute interval for an hour. Propose and tabulate the suitable concentrations of dinitrogen pentoxide for each interval in order to get ideal rate of reaction plot. By using the compiled data, calculate the concentration of the products and construct a graph to represent this data. Estimate the rate of decomposition for the reactant and the formation of products over the entire 60 minutes. Propose examples of properties, directly related to reactant or products, that could be used to measure a reaction rate. 1. a.
