power coefficients

Expression for the equilibrium constant of a reaction is written in the form of a ratio. The numerator consists of the molar concentration (or partial pressure) terms of the products each raised to a power equal to its stoichiometric coefficient in the balanced chemical eq..

Solubility product Ionic product It is the product of the concentration of ions of the electrolyte each raised to the power of their coefficients in the balanced chemical equation in a saturated solution It is the product of the concentration of ions of the el..

For the second term, take coefficient as n C 1 , decreases the power of 'a' by 1 and increases the power of 'b' by 1. Thus, the second term is n C 1 a n - 1 b 1..

Method of writing expansion for (a+b) n The first term in the expansion of (a + b) n is n C 0 a n b 0 . For the second term, the coefficient is taken as n C 1 , the power of 'a' is decreased by one and the power of 'b' is increased by one. So, the second term i..

For the third term, take coefficient as n C 2 , power of 'a' as n-2 and power of 'b' as 2. Continue this process repeatedly till the last term n C n a 0 b n is obtained..

For the third term, take coefficient as increase the power of x by 1. Thus, the third term is Repeat this process repeatedl..

Consider a reversible reaction expressed by the following general equation: where A and B are two substances which react to form new substances C and D and C and D react under the same conditions forming the original substances A and B. Let us assume that the concentrations of these four substances..

. The thermo emf increases with temperature and reaches a maximum value at a certain temperature, called the neutral temperature T n . The value of the neutral temperature is constant for a thermocouple, depends on the nature of materials and is independent of the temperature of the cold junction. ..

Order of a Reaction - The order of reaction is determined with respect to each reactant in the reaction. The order of a reaction is the power to which the concentration of a reactant is raised. This is the order with respect to one reactant only. For the reaction where there are more than..

Rules for Writing Equilibrium Constant Expressions - Expression for the equilibrium constant of a reaction is written in the form of a ratio. The numerator consists of the molar concentration (or partial pressure) terms of the products each raised to a power equal to its stoichiometric ..
