Respuesta :
B) A catalyst must be in contact with the reacting molecules for a reaction to occur.
What is meant by the collision concept?
Collision theory is the principle used to are expecting the charges of chemical reactions, mainly for gases. The collision principle is based totally on the assumption that for a response to occur it's far essential for the reacting species (atoms or molecules) to come together or collide with one another.
The collision power needs to be extra than the activation electricity for the response. The collision should arise within the proper orientation. The collision frequency needs to be extra than the frequency factor for the reaction. A collision among the reactants should arise.
Some other visible example of a collision idea is billiard balls at some point in a sports pool. Billiard balls collide with every different, similarly to the fuel particles within the field of air. The cue ball needs to strike the billiard ball with proper orientation and energy to get that ball into the pocket.
