Question

chem help please !!
Does anyone know how to create potential energy diagrams for chemical reactions?

https://prnt.sc/nao4fe

Can someone help me create these diagrams... its a little confusing to me

Answer 1

like the prompt says, potential energy goes on the y-axis and reaction progression goes on the x-axis

Answer 2

plot the energy of your reactants and the energy of your products, making sure your axis is to scale

Answer 3

activation energy is the energy diff. between the reactants and the transition state

Answer 4

transition state is the label that we give to the chemical species at the top of the activation energy curve

Answer 5

connect with a smooth curve (sorry if it's a bit shakey, i'm using a trackpad)

Answer 6

then, total change in enthalpy (deltaH) is just the energy change between reactants and products

Answer 7

I hope the process makes a bit more sense now. if you have questions or want me to check your solutions on the other two graphs I would be happy to.

Answer 8

Sorry for the late reply! This makes a lot more sense to me! Are you able to help with just the plotting on the other two graphs? I am very terrible at that.

Answer 9

I mean it's just the same process w/ different #'s

Answer 10

okay I got it and how do I know the reaction progress (or time) ? so I can plot the graphs? Im not sure if im just passing over that or what.

Answer 11

you don't, you just put that on the x-axis since it's the independent variable
the units on the time are irrelevant unless given in the problem

Answer 12

Ok this is terrible and its really hard to use the drawing thing but would this somewhat look like what the Synthesis reaction diagram would look like? and obv I didn't plot the the entire thing... I plan on just drawing the graph myself but jw

Answer 13

and thats not a -25 btw o:
