Write a two to four sentence conclusion statement explaining how the potential energy diagram is used to identify if the reaction is endothermic or exothermic, if heat was released or absorbed, and why the sign of enthalpy change was positive of negative. There should be a conclusion statement for each graph.

Generic Reactions Reactants Products Transition State
Synthesis
A + B → AB A + B −15 kJ AB 20 kJ 30 kJ
Single Replacement
C + AB → CB + A
C + AB 65 kJ CB + A 30 kJ 85 kJ
Double Replacement
AB + CD → AD + BC AB + CD 10 kJ AD + BC 60 kJ 75 kJ

if its absorbed then its endo to exot then it relases or obsobed

Explanation:

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
