Question

I am given the two equations:
Cl₂(g)+F₂(g) 2ClF(g)
ClF(g)+F₂(g) ClF₃(g)

Question:
a) Write overall equation
b) Show that the overall K_c equals the product oftheK_c's for the individual steps

Results:
a) Cl₂(g)+3F₂(g) 2ClF₃(g)

- My professor gave me this answer but he showed no steps onhow toget to that. When i tried to solve it i was cancelingtheF₂'s out. This does not seem to be the way to solveit.Could you explain how he got that?

b)K₁=[ClF]²/[Cl₂][F₂]
K₂=[ClF₃]/[ClF][F₂]
K_T=K₁x K₂=[ClF₃]/[Cl₂][F2]³

- I did not know how to get the overall equation from question asothis might be why i do not understand this result. Couldyouexplain in steps why this is?
