Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.
Those who wish to adopt the textbooks are required to send a request to NCERT, upon which soft copies of the books are received. The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores.

Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The molecular orbitals are labelled according to their symmetry, [e] rather than the atomic orbital labels used for atoms and monatomic ions; hence, the electron configuration of the dioxygen molecule, O 2, is written 1σ g 2 1σ u 2 2σ g 2 2σ u 2 3σ g 2 1π u 4 1π g 2, [39] [40] or equivalently 1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g ...
[2] Bhave wanted peasants to give up using bullocks, tractors, or other machines for agricultural purposes. This was called rishi-kheti in Hindi. Bhave also wanted the people to give up using money in the form of kanchan-dan. The movement had the support of Congress. JP Narayan withdrew from active politics to join the Bhoodan movement in 1953.
In a 2019 article, discussing the award-winning film 1917 (2019), Eric Grode of The New York Times wrote that very long takes were becoming popular in more mainstream films "as a sobering reminder of temporality, a virtuosic calling card, a self-issued challenge or all of the above", also citing the Academy Award-winner from several years prior, Birdman (2014).
The report estimates that chemical CO 2 absorption would cost $35/t of CO 2, plus $8–20/t CO 2 for transportation and storage. [95] At the time, this would have increased steel production costs by 15–20%, [ 88 ] [ citation needed ] presenting a barrier to decarbonisation for steelmakers which typically operate with margins of 8–10%.

Shudra or Shoodra [1] (Sanskrit: Śūdra [2]) is one of the four varnas of the Hindu class and social system in ancient India. [3] [4] Some sources translate it into English as a caste, [4] or as a social class. Theoretically, Shudras constituted a class like workers. [2] [5] [6]
