प्रश्न

Find out the value of Kc for each of the following equilibria from the value of Kp:

\[\ce{CaCO3 (s) ⇌ CaO(s) + CO2(g)}\]; Kp= 167 at 1073 K

संख्यात्मक

उत्तर

Here,

Δn = 2 - 1 = 1

R = 0.0831 barLmol-1K-1

T = 1073 K

Kp= 167

Now,

Kp = Kc (RT) Δn

`=> 167 = "K"_"c"(0.0831 xx 1073)^(triangle"n")`

`=> "K"_"c" = 167/(0.0831 xx 1073)`

= 1.87 (approximately)
