1.	Choose the incorrect statement.(a) In equilibrium mixture of ice and water kept in perfectly insulted flask, mass of ice and water does not change with time(b) The intensity of red colour increases when oxalic acid is added to a solution containing iron (III) nitrate and potassium thiocyanate(c) On addition of catalyst the equilibrium constant value is not affected(d) Equilibrium constant for a reaction with negative .H value decreases as the temperature increases.
Answer» (b) The intensity of red colour increases when oxalic acid is added to a solution containing iron (III) nitrate and potassium thiocyanate Oxalate ions of oxalic acid form complex with ferric ions thus decrease its concentration thus, concentration of red complex in product decreases.

(b) The intensity of red colour increases when oxalic acid is added to a solution containing iron (III) nitrate and potassium thiocyanate

Oxalate ions of oxalic acid form complex with ferric ions thus decrease its concentration thus, concentration of red complex in product decreases.
