Question

explain about collision theory

Answer 1

Answer:

Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.

Answer 2

Answer:

These stars are mistakenly referred to as G-type stars. Our Sun is a G-type star, but it is in fact white. G-type stars convert hydrogen into helium and usually evolve into red giants when their hydrogen fuel is exhausted. Some examples are: Alpha Centauri A, Tau Ceti.

Orange Dwarfs

These stars have a prevalence of around 10%, with a spectral type K. They have temperatures between 3.700 K to 5.200 K, with luminosities around 0.08 to 0.6 that of the Sun. They have a mass of 0.45 to 0.8 that of our sun and last around 15 to 30 billion years.
