An important reaction for the conversion of natural gas to other useful hydrocarbons is the conversion of methane to ethane. 2ch4(g)→c2h6(g)+h2(g) in practice, this reaction is carried out in the presence of oxygen, which converts the hydrogen produced to water. 2ch4(g)+12o2(g)→c2h6(g)+h2o(g)

6) (a) calculate the absorbance of the solution if its concentration is 0.0278 m and its molar extinction coefficient is 35.9 l/(mol cm). the depth of the cell is 5 mm. (b) what is the %t? (7) calculate the absorbance of the solution if the transmitted light intensity is 70% of the initial light beam intensity
