Question

The followingreaction is exothermic:   3NO(g) N2O(g) +NO2(g)
Predict the effect of each of the following stresses on theposition of the equilibrium mixture by circling the correctphrase.
(a)NO(g) is added to the equilibrium mixture without change of volumeor temperature. (shifts left, shifts right ornoeffect)                                                                                                                               b)N2O(g) is removed from the equilibrium mixturewithout change of volume or temperature. (shifts left,shifts right or no effect)
(c)the volume of the equilibrium mixture is increased at constanttemperature. (shifts left ,shifts right noeffect)
(d)the temperature of the equilibrium mixture is increased.(shifts left, shifts right or no effect )
(e)adding a catalyst to the reaction mixture. (shifts left,shifts right or noeffect)
(f)gaseous argon is added to the equilibrium mixture without changingthe volume (shifts left, shifts right or noeffect) The followingreaction is exothermic:   3NO(g) N2O(g) +NO2(g)

(f)gaseous argon is added to the equilibrium mixture without changingthe volume (shifts left, shifts right or noeffect)

Explanation / Answer

(a) Shift to the right (Adding NO will resulting in NO beingconsumed to shift the equilibrium to the right) (b) Shift to the right (Remove N2O favours the side towith N2O) (c) Shift to the left (increase volume favours the side with moremols of gas) (d)Shift to the left (favours endothermic reaction) (e) No effect (Catalyst does not affect equilibrium) (f) No effect (inert gas has no effect on equilibrium as inert gasis not reactive at all) Hope this helps!
