An improvised meteor flare composition consists of polyisoprene, potassium nitrate, and sulfur. Answer he following questions. 1. Calculate the enthalpy of reaction per unit of mass (i.e., per kg ) of each of the following molar ratios (for polyisoprene, one mole is one mole of isomer units). Assume all hydrogen atoms form water and the leftover oxygen atoms are distributed among CO,CO2, and K2CO3 to make the reaction balance. Which composition is the most exothermic? (12 points) a. 6KNO3+2C5H8+3S b. 4KNO3+C5H8+2S c. 6KNO3+C5H8+S 2. For the three compositions above, give the mass ratios of the three components. ( 6 points) 3. For the three compositions above, assume that products containing potassium ( K ) are solids and all others, including water, are gas. For each composition, how many moles of gas per unit of mass are produced? ( 12 points)
