Decay of organic matter such as vegetation or chemical reaction with sulphur containing mineral in rock and soil produces gas which has rotten egg smell. Calculate the percentage dissociation of the gas produced by the sulphur reducing bacteria if dissociation constant (Kc) of the gas is 1.0 x 10^6. There are 0.1 moles of the gas in 1.6 dm³ vessel.
i. Write the equation for dissociation of the gas produced in the reaction.
ii. If x moles of the gas are dissociated, write the expression for equilibrium constant in terms of x. (Detail working expected)
iii. Calculate the value of x and hence percentage dissociation.
