Question
The gas-phase conversion of nitric oxide and hydrogen to nitrogen and water follows the reaction
k
NO(g) + H2(g) ½ N2(g) + H2O(g)
The rate of production of nitrogen as a function of initial reactant pressures is shown in the table at right. Is this reaction favorable under standard state conditions?
Select one:
Can't tell from the information given
It is favorable in the direction written
It is favorable in the opposite direction to the way it is written
The rate of production of nitrogen as a function of initial reactant pressures is shown in the table at right. Is this reaction favorable under standard state conditions?
Run P0 H2(kPa) P0 NO (kPa) Rate (kPa/s) 1 53.3 40.0 0.137 2 53.3 20.3 0.033 3 38.5 53.3 0.213 4 19.6 53.3 0.105Explanation / Answer
The reactant side has 2 molecules and the product side has 1 and half molecule. The effect of pressure in the the above said reaction favours formation of profucts, because a few gas molecules are required to occpy less volume.
