Choose the incorret statement.

Answer»

In equilbirium mixture of ice and WATER kept in PERFECTLY in perfectly insuled flask. Mass of ice and water does not change with time
The intensity of red colour increase when oxalic acid is ADDED to a solution containing iron (III) nitrate and potassium thiocyanate
On addition of catalyst the equilibrium constant value is not affected
Equilibrium constant for a reaction with negative `Delta H` value decrease as the timperature increases.

Solution :Oxalate ions of oxalic acid from comples with FERRIC ions thus decrease its concentration thus, concentration of red COMPLEX in product decreases.
