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?

1 answer

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

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