Question

2. This graph shows the energy changes during the progress of a reaction involving two molecules. Explain what is happening or what the state of the reaction is at A, B, C, and D. Is this an exothermic or an endothermic reaction?

Answer 1

which graph?

Answer 2

im working on that part lol

Answer 3

lol oh ok

Answer 4

i couldnt figure out how to post the graph so i posted the link

Answer 5

If the reactants are of higher energy than the products (higher on the graph) then it's an exothermic reaction. The converse is also true.

A is the reactants, B is the transition state, C is the products.

D is the difference in energy between the reactants and the transition state, it's called Activation energy, \(E_a\).

Answer 6

where is the graph? on the link?
