Question

Consider the reaction, which takes place at a certain elevated temperature CO(g)+NH3(g)⇌HCONH2(g), Kc=0.690 If a reaction vessel initially contains only CO and NH3 at concentrations of 1.00 M and 2.00 M, respectively, what will the concentration of HCONH2 be at equilibrium?

Answer 1

Answer:

The concentration of HCONH2 in equilibrium is 0.55M

Explanation:

Answer 2

Answer:

0.504 M

Explanation:

0.680 = x/(1.00-x)(2.00-x)

0.680 = x/(2-3x+x2)

0.680x2 - 2.04x+ 1.36 = x

0.680x2-3.04x+1.36=0

either 3.96 or 0.504

it would not be 3.96 which would give you a negative so it would be 0.504 M the answer.
