Question

Please help. 3. This graph shows the energy involved in a reaction involving two molecules. Describe what is happening or what the state of the reaction is at A, B, C, and D. Then tell if this is an exothermic or an endothermic reaction. Ill post the graph next.

Answer 1

So at A you have the reactants, then up the hill you have the transition state, then at C you have the products.

Answer 2

what about D?

Answer 3

D is the energy necessary for the reactants to come to the geometry of the transition state, it's called Activation Energy

Answer 4

oh thank you! just one last question, would this be an endothermic or exothermic reaction?

Answer 5

The reactants are higher on the y axis (whihc is energy) than the products, so energy is released to the surroundings.

Answer 6

so endothermic?

Answer 7

released is exo

Answer 8

absorbed is endo

Answer 9

thank you so much!

Answer 10

How do elements on the right side of the periodic table differ from elements on the left side of the table?

Elements on the right side are much less reactive. Elements on the right side can form compounds and those on the left cannot. Elements on the left side are metals and those on the right side are nonmetals. Elements on the left side have more neutrons.
