how much oxygen is required to convert total so2 into so3 tell me the percentage ratio of so2:o2
the reaction is so2+1/2o2=so3
each O2 reacts with 2SO2, so in moles, the ratio would be 2:1
in mass, convert from moles to grams.
To determine the percentage ratio of SO2 to O2 in the reaction SO2 + 1/2 O2 → SO3, we need to consider the stoichiometry of the reaction.
The balanced equation shows that for every 1 mole of SO2 consumed, 1/2 mole of O2 is required to produce 1 mole of SO3.
Therefore, the ratio of SO2 to O2 in terms of moles is 1:1/2 or 2:1.
To convert this ratio to a percentage ratio, you need to find the sum of the parts, which in this case is 2 + 1/2 = 2.5.
To determine the percentage ratio, you can divide each part of the ratio by the sum and multiply by 100.
SO2: (2/2.5) x 100 = 80%
O2: (1/2.5) x 100 = 40%
Therefore, the percentage ratio of SO2 to O2 in the reaction is approximately 80% : 40%.
