Theoretically, the yield of sua(g) may be increased by using
(a) more air, (because it is cheap and available),
(b) a low temperature (because forward reaction is exothermic), (c) à high pressure (becaise no. of moles of gas on the left-handed side is greater),
However, the reaction is too stow. if the temperature is too low and it is too expensive to build a reaction chamber to stand against too large pressure.

Solution to Q.11.1 (a):D/The rate is increased:: (ii) The rate, is increased. (iii) The rate is increased. (b)(i): Decreased. It is because the
forward reaction is endothermic and a decrease in temperature shifts the equilibrium position to the

{11) Decreased. It is because there is a greater number of moles of gaseous substances or the right-handed side, so. a increase in pressure shifts the equilibrium positior to the left..
(iii) No effect. It is because a ': catalyst speeds up both the forward and reverse reaction to the same extant...
(iv) Increase. It is because, an increase in pressure of steam will shift the equilibrium position to the right.
