Name two devices which do not obey Ohm.s law.

a) For the oxidation of iron 4 Fe_((s))+3O_(2(g))rightarrow2Fe_2O_(3(s)) , entropy change is -549.4 JK^-1mol^-1 at 298 K. Inspite of the negative entropy change of this reaction, why is the reaction spontaneous? ( DeltaH_r^0 for the reaction is - 1648xx10^3Jmol^-1 ). b) Write the difference between extensive and intensive properties. Give one example of each.
