The attractive intermolecular forces are called vander Waals’ force. in honor of Dutch scientist Johannes van der Waals (1837-1923) as he explained the deviation of real gases from the ideal behaviour through these forces.
Van-der Waals’ s forces vary considerably in magnitude and include , dispersion forces or London forces, dipole-dipole forces, and dipole-induced dipole forces.

TC and TVC curves are parallel to each other and the vertical distance between them remains the same at all levels of output because the gap between them represents TFC which remains constant at all levels of output.

Rate law
- The representation of rate of reaction in terms of molar concentration of the reactants participating in a reaction raised to some power is called rate law.
- It is also called rate expression or rate equation.
- Consider a reaction:
2NO (g) + O2 (g) --> 2NO2
Rate ∝ [NO]2
Rate ∝ [O2]
Combining these two rates we derive
Rate ∝ [NO]2 [O2]
Rate =k [NO]2 [O2]
- Where k is the proportionality constant with a definite value at a specific temperature for a specific reaction and is called Rate Constant.
- Rate law expression = -d[R]/ dt = k [NO]2 [O2]

मानव बस्ती किसी भी प्रकार और आकार के घरों का संकुल है जिनमें मनुष्य रहते हैं। एक स्थान जो साधारणतया स्थायी रूप से बसा हुआ हो उसे मानव बस्ती कहते हैं। मानव बस्ती का अध्ययन मानव भूगोल का मूल है क्योंकि किसी भी क्षेत्र में बस्तियों का रूप उस क्षेत्र के वातावरण से मानव का संबंध दर्शाता है।

3a+(-a+b)+(-a+c)
= 3a - a + b - a + c
= 3a - a - a +b +c
= a + b + c
