Question

This is my second time asking this question, the first one provided is incorrect.

For the chemical equation
SO, (g) + NO, (g) = S0,(g)+NO(g)
the equilibrium constant at a certain temperature is 2.60. At this temperature, calculate the number of moles of NO, (g) that must
be added to 3.36 mol SO, (g) in order to form 1.40 mol SO,(g) at equilibrium.
.224
moles of NO, (g):
mol
Incorrect

Expert Solution
Step 1
SO2(g)+NO2(g)----SO3(g)+NO(g)
For the reaction, keg = [Product]/[Reactant] = [SO3][NO]/[SO2][NO2]
%3D
Keg = 2.6; [SO2] = 3.36 ; [SO3] = 1.4 = [NO]
Step 2
[NO2] = [SO3][NO]/[SO2]keg = (1.4x1.4)/(3.36x2.6) = 0.224 mol
