Q1. (23 pts total) A wide range of chemical substances can pollute the air. NO,, mainly includes NO and NO, is a type of major pollutant generated from road traffic and fossil fuel combustion processes. NO, (g) may react with another pollutant in the combustion engine, co(g), and regenerate NO(g). The reaction is described below: NO (g) + CO(g) → NO(g) + CO, (g) a) (5 pts) If the activation energy for this process is 132 kJ/mol, how many times...

Nitrogen oxide, NO, is a common pollutant produced by the reaction of nitrogen and oxygen gas. Since these gases are several major components of air, nitrogen oxide forms when air is heated in furnaces, engines and other high temperature combustion reactions. Given the standard enthalpy of formation for NO (g) = 90.25 kJ / mole and using the absolute entropies shown in the table below, the free energy change for the reaction at 25.00 ºC can be calculated, and equals...
