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..

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..

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..

Working rules for expanding (a + b) n n N: Step 1: The value of index, n implies that there will be n+1 terms in the expansion of (a + b) n . Step 2: Write the first term: n C 0 a n b 0 . Step 3: For the second term, take coefficient as n C 1 , decrea..

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 one reactants, the or..

When the coefficient of the highest power is 1. i.e., ax 2 bx c, when a = 1 and b and c are integers. When two binomials are multiplied the product is a trinomial. Thus (x + 4) (x + 5) = x 2 + 9x + 20 (1) (x - 4) (x - 5) = x 2 - 9x + 20 (2) In this chapter we try t..

Conservative Forces and Non-Conservative Forces - Let us consider two situations Suppose a block of mass 'm' rests on a rough horizontal table. It is dragged horizontally towards right through a distance 'l', and back to its initial position. Let ' m ' be the coefficient of friction betwe..
