b) Adding C
c) Lowering the temperature
d) Increasing pressure
e) Adding a catalyst
2. At a certain temperature, K₂ = 3 for the reaction
NO3(g)
NO(g) + O2(g)
Find the direction of the reaction if at some point in time in a 1.0 vessel the
following respective concentrations were measured; [NO] = 2.0 mol/L,
[0₂] = 1.0 mol/L and NO3(g) = 0.75 mol/L.
