1. Combustion reactions involve the burning of a hydrocarbon, or the reaction of that hydrocarbon with oxygen to produce carbon dioxide and water. For example, butane 13 2g) -> 4CO2(g) +51I20(g) CAH (g) (1) Combustion reactions are exothermic, since the reaction releases energy as heat a) Using the van't Hoff equation, predict the impact on the equilibrium constant for this reaction if the temperature is increased, at constant pressure b) Butane is commonly used in portable grills as a fuel...
