Question

In the system X + 2Y Z, the equilibrium concentrations are,

Find the equilibrium constant of the reaction.

• A. 250
• B. 500
• C. 125
• D. 273

Answer 1

Answer: (A)

250

Answer 2

: X + 2Y Z

$0.06$ $0.12$ $0.216$

$\mathrm { K } _ { \mathrm { c } } = \frac { [ \mathrm { Z } ] } { [ \mathrm { X } ] \mathrm { Y } ] ^ { 2 } }$ $= \frac { 0.216 } { 0.06 \times 0.12 \times 0.12 } = 250$
