Answer:

<h2> concentration of HCONH2 at equillibrium is 0.5 M</h2>

Explanation:

                               CO(g) + NH3(g) ⇌ HCONH2(g)

-vessel iniatial             1             2                 0

concentration

-equillibrium              1-x         2-x               x

concentration

                                K_{C} = (CO)\times (NH_{3})/ (HCONH_{2})

                               0.860 = (1-x)(2-x) / x

                                 x^{2}-3.86x+2

                                  x = 3 , 0.5

         concentration of HCONH2 at equillibrium is 0.5 M
