NO is produced in the atmosphere at moderately low partial pressure by high temperature combustion. What is its fate as cooling occurs? To help address the question, calculate the equilibrium constant at 298 K and 1300 K for each reaction:
½ O2(g) + NO(g) <---> NO2(g)
2 NO2(g) <---> N2O4(g)
11 g of sodium bromide NaBr is mixed with 9 g of butanol CH3CH2CH2CH2OH to yield 258 mg of bromobutane CH3CH2CH2CH2Br. Under the catalysis of 10 ml of sulfuric acid density 1.84g/ml.
