Question

Part B The last step in the production of nitric acid is the reaction of nitrogen dioxide with water: If 65.0 g of nitrogen dioxide is reacted with excess water, calculate the theoretical yield. Express your answer to three significant figures and include the appropriate units NO2(8) +H20()+HNOs(aq)+ NO(g) m= 1 Value ll Units Submit Request Answer Part If only 43.8 g of nitric acid is obtained, calculate the percent yield Express your answer to three significant figures and include the appropriate units. alue Units Submit Request Answer Provide Feedback

Explanation / Answer

3NO2(g) + H2O ------------> 2HNO3 + NO

3 mole of NO2 react excess of H2O to gives 2 mole of HNO3

3*46g of NO2 react with excess of H2O to gives 2* 63g of HNO3

65g of NO2 react with excess of H2O to gives =2* 63*65/3*46   = 59.35g of HNO3

Theoretical yield of HNO3 = 59.35g

actual yiled of HNO3   = 43.8g

percentage yiled   = actual yiled *100/theoretical yiled

                              = 43.8*100/59.35 = 73.8% >>>>>answer
