When we have this equation: 
             CO(g) + Cl2(g) ↔ COCl2(g)
intial   0.147       0.175              0
change -X           -X                 +X
final   (0.147-X)   (0.175-X)          X

so from the ICE table, we substitute in Kc formula :(when we have Kc = 255)

Kc = [COCl2]/[CO][Cl2]
255= X / (0.147-X)(0.175-X)
255 = X / (X^2 - 0.322 X + 0.025725)
X = 0.13
∴[CO] = 0.147 - X = 0.147 - 0.13 
           = 0.017 m

Q 9.3: how many triplets would you expect to observe in the 1h nmr spectra for o-chlorotoluene
agasfer [191]
Hello!

You would expect to observe 2 triplets in the ¹H NMR spectra for o-chlorotoluene. 

Multiplicity observed in ¹H NMR spectra when the atom couples with a neighbor ¹H atom. The multiplicity is equal to N+1 where N is the number of neighbor atoms. 

To observe a triplet, you'll need a molecule with 2 neighbor atoms. In o-chlorotoluene (shown in the figure), only protons C and D have 2 neighbor atoms (B and D; A and C, respectively), so you'll expect to see a 2 triplets. 

Have a nice day!

The standard plate count is used to determine the total number of bacteria present in a specified amount of milk, usually a milliliter (mL). This is used for the grading of milk. The coliform plate count is widely used to determine the total number of coliforms present in one mL of milk sample.
