Sulfur trioxide is a gas that reacts with liquid water to produce aqueous sulfuric acid, or acid rain. What is the equation for this reaction?

Respuesta :

SO3+H2O-->H2SO4
If you need their states
SO3(g) + H2O(l) --> H2SO4(aq)
And they're already balanced 

Answer:

NO is the catalyst.

NO is the catalyst because it increases the rate of the reaction but is not consumed during the reaction.

NO increases the rate of the reaction by lowering the activation energy.

The reaction of NO with O2 provides an alternative reaction pathway with a lower activation energy.
