24) When Q < Kc , reaction proceeds in forward direction i.e to produce more product.
Therefore, answer is A.
25) Oxidation state of Fe in FeCl2
Oxidation state of Cl = -1
Le, oxidation state of Fe be x
So, x + (-2) = 0
X = +2
Therefore answer is B
26) When temperature increases, molecules moving more rapidly collide with one another more often in a fixed amount of time and with greater energy, leading to an increase in reaction rate.
Therefore, answer is A
27) Oxidation occur at anode of spontaneous galvanic cell.
Therefore, answer is A

Molten salts When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. The electrolysis of CaBrz (), for example, produces Ca(s) at the cathode (from the reduction of Ca2+) and Br2(1) at the anode (from the oxidation of Br"). If more than one cation is present, only the one with highest reduction potential will be reduced. Similarly, if more than one anion is present, only the one with the highest...
