k - capture
In some nuclides, the nucleus may capture an electron from the K - shell. The vacancy created is filled by electrons from higher levels giving rise to characteristic X - rays. This process is known as K - electron capture or simply K - capture. An example of k..

When the value of K is equal to one, both the directions of the reaction are almost equally favoured. In such cases, the equilibrium concentration of the reactants and products are comparabl..
Effect of temperature on K
The value of Kw varies with the change in temperature. The values of [H 3 O + ] and [OH - ] are always equal to each other at all temperatures but the values of K w are different at different temperatures. The value of K w increases with the rise in temperature. This is be..

Degree of dissociation ( a ) at a particular concentration c is related to the dissociation constant (K..
When K » 1
When the value of K is very high such as, 10 7 -10 1 5 or more, the reaction proceeds to almost completion. In such reactions almost the whole of the reacting substance gets converted into product..
Measurements of Specific Conductivity (k)
Resistance is measured using the principle of a wheat stone bridge. It consists of four arms. fig 5.4 - Principle of D.C Wheatstone bridge method R 1 - Variable resistance R 2 - Unknown resistance G - Galvanometer. Knowing R 1 , R 3 and R 4 , R 2 can be calculated. ..

Very good patient and encouraing than my school teacher. I would love to study with tutor vista rather than going to school.
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
The tutors have a wonderful attitude for teaching math. They also wants you to be able to understand all of the concepts. They is better than my regular instructor in my school. TutorVista is the best! - Cody
It was very fun. My tutor was very helpful & patient with me. I am able to understand the concepts better. -Kelvin
