Question

A sample of phosgene gas at an initial concentration of 0.500 m is heated at 527 °c in a reaction vessel. at equilibrium, the concentration of co (g) was found to be 0.046 m. calculate the equilibrium constant for the reaction at 527 °c.

Answer 1

Answer : The equilibrium constant will be - 0.454

Explanation : The reaction is given below;


`COCl_(2) \ \textless \ ----\ \textgreater \ CO + Cl_(2)`

We need to find Equilibrium constant -
`K_(c)`;


`K_(c)` = [CO] [
`Cl_(2)`] /
`[COCl_(2) ]`

So,
`K_(c)` = [0.046] X [0.046] / [0.5 - 0.046]

Therefore,
`K_(c)` = 0.454
