Calculate the freezing point of the solution when 31 g of ethylene glycol C 2 H 6 O 2 is dissolved in g of water. The rate constant of a first order reaction increases from 2 — 10 -2 to 4 — 10 -2 when the temperature changes from K to K. Calculate the energy of activation E a. Define the following terms: i Brownian movement ii Peptization iii Multimolecular colloids. Calculate E. The conductivity of 0. Molar conductivity. In primary batteries , the charging reaction occurs only once and after it has been used over a period of time , the battery becomes dead and cannot be refused mercury cell is more advantage than dry cell has a very short life span due to the conversion of zinc to zinc chloride that makes the zinc casing porous. Due to this porous casing, the substance inside the cell leaks out and corrodes the metal, reducing the lifetime of the cell. While, in the case of mercury cell, the overall reaction does not involve the formation of any ion in the solution whose concentration can change during its life time. Subject Chemistry. Pre Boards.

Electrochemistry is a branch of chemistry, and it deals with the study of the production of electricity from the energy released during spontaneous chemical reactions and the use of electrical energy to bring about non-spontaneous requiring the input of external energy chemical transformation. Electrochemistry deals with how much chemical energy produced in a redox reaction can be converted into electrical energy. A redox reaction is that in which oxidation and reduction take place simultaneously. The arrangements used to bring about the chemical transformations are called electrochemical cells. The cells are used to convert chemical energy into electrical energy and electrical energy into chemical energy. There are two types of electrochemical cells :.
