3O₂(g) + 4NO(g) ----> 2N₂O₅(g)

Rate of the reaction = rate of disappearance of reactants = rate of appearance of products

Â Â r = -(1/3)xd[O₂]/dt = -(1/4)xd[NO]/dt = +(1/2)xd[N₂O₅]/dtÂ Â Â Â Â Â Â -----(1)

Given d[O₂]/dt = 0.057 mol/L.sec

From Eqn(1) , -(1/3)xd[O₂]/dt = -(1/4)xd[NO]/dt

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â d[NO]/dt = (4/3)xd[O₂]/dt

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = (4/3) x 0.057

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 0.076 mol/L.sec

-(1/3)xd[O₂]/dt = +(1/2)xd[N₂O₅]/dtÂ Â Â

d[N₂O₅]/dtÂ Â = (2/3)xd[O₂]/dt

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = (2/3) x 0.057

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 0.038 mol/L.sec
