Question

A- Now consider a complex formed by two molecules; under what conditions would the complex come apart into two separate molecules?

Y-axis is potential energy and X-axis is distance

B- What forces would be involved and why are these forces present?

C- How would temperature changes influence the stability of such a complex?

For example, what is likely to happen to the complex as the system temperature increases?

- it stability would increase

- it stability would decrease

- there would be no effect on the stability

D- Please explain your choice. What ideas or facts influenced your thinking?

Answer 1

The answer is given below

Yoo 9 Po 14 apart be For Complex Come molecules : This can Day - 4 He know: IT.E = KE+PE / into two separate explained by two FF - Do When the then become two KE is going value to P.E PE reached zero then molecules. tower and lower then al increased . At one point maximum sealue and KIE a complex Seperate into When b/w to molecules in complex Attractive force become maximum At that point too Complex separate into molecules A is that point where two seperate molecule present *

1 6 What Force and why? -F with derivative of d distance pokental known Energy negative The first respect value of to Force here * There are Altractive Repulsive two force force type of of force attraction y attraction, # At point B - U=0 positive - So. At point B No Force is there. As we move B A Slope of curve so Force value is negative and As high value of Force is negative Attractive force will work. un As we move Bn slope g curve is negative negative so force is positive as high value of force is positive Repulsive force will take place. So B - A = Attractive force olmo B c . Repulsire force.

I Temp effect - into higher ation take Stability of Due to increase of temp get energy so they Energy level so due to place so By increase of complex Decrease molecules jumped this expenda temp Te >ti 9 increased distance 9. Ул, internuclear means so stability decreased by temp. increasing of Energy case Simpe D: this In and case Energy lereh simpe Force, influenced
