Formamide, HCONH2, is used to manufacture agricultural chemicals, dyes, and pharmaceuticals. At 125 degrees Celcius, formamide decomposes.

HCONH2 <--> NH3 +CO
if Keq is 4.8 and the concentrations of NH3 and CO are both .20 mol/L at equilibrium, what is the concentration of formamide?

....................HCONH2 <--> NH3 +CO

Keq = (NH3)(CO)/(HCONH2) = 4.8
Plug in concn NH3 and CO and solve for (HCONH2).

To determine the concentration of formamide, we can use the equilibrium expression and the given equilibrium concentrations of NH3 and CO.

The equilibrium expression for this reaction is as follows:
Keq = [NH3] * [CO] / [HCONH2]

Given that Keq is 4.8 and the concentrations of NH3 and CO at equilibrium are both 0.20 mol/L, we can substitute these values into the equation:
4.8 = (0.20) * (0.20) / [HCONH2]

To find the concentration of formamide ([HCONH2]), we can rearrange the equation:
[HCONH2] = (0.20) * (0.20) / 4.8

Calculating this expression will give you the concentration of formamide.
