In the reactions,

A + 2B\leftrightharpoons2C

, if 2 moles of

A

, 3.0 moles of

B

and 2.0 moles of C are placed in a 2 L flask and the equilibrium concentration of

C

is 0.5 mol/L, the equilibrium constant

\left( {{K_c}} \right)

for the reactions is

View answer and explanation

Correct option: A

0.21

Option A (

0.21

) is correct because after calculating the equilibrium concentrations, the equilibrium constant Kc is found to be approximately 0.21.
