Suppose a particle is moving in such a way that its average velocity, measured for a number of different time intervals, is not constant. This particle is said to move with variable velocity. Then, we must determine a velocity of the particle at any..

Another French chemist, Joseph Proust, stated this law as 'A chemical compound always contains same elements combined together in the same proportion by mass'. For example, pure water obtained from different sources such as river, well, spring, sea, etc., always contains hydrogen and oxy..

Reaction Quotient and the Equilibrium Constant - The concentration ratio, i.e., the ratio of the product of concentration of the products to that of the reactants at any time (t) is known as the concentration quotient 'Q' of the reaction at time (t). The value of Q c or Q p will be d..
