Question

In which of the following reaction the value of K_p will be equal to K_c?

पर्याय

• \[\ce{H2 + I2 <=> 2HI}\]

• \[\ce{PCl5 <=> PCl3 + CI2}\]

• \[\ce{2NH3 <=> N2 + 3H2}\]

• \[\ce{2SO3 <=> 2SO2 + O2}\]

Answer 1

\[\ce{H2 + I2 <=> 2HI}\]

Explanation:

The K_p = K_c are related by formula `"K"_"p" = "K"_"C" ("RT")^"n"`

For K_p = K_c 

Δ n = 0

`"n"_"product" - "n"_"reactant"` = 0

1. Δ n = 2 - 2 = 0
2. Δ n = 2 - 1 = 1
3. Δ n = 4 - 2 = 2
4. Δ n = 3 - 2 = 1
