What is the mole ratio between FeCl3 and Fe(C5H7O3)3 ?

     162.2 g FeCl3. mL of soln = 0.07028 mol FeCl3x ... mol FeCl3 = mol Fe(OH)3 = 0.01291 mol ... (a) MaVa = MbVb since HCl and KOH react in a 1:1 molar ratio.

Explanation:

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
