Estimate the vapor pressure of ethanol at temperatures of t = 0, 50, 100 and 150 c using the following methods: a. the antoine equation b. the clausius – clapeyron equation with dhvap = 42 kj/mol at the normal boiling point of t= 351.5 k c. the shortcut equation d. for each temperature, identify the estimate you consider the most accurate, and explain why?

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
