For the reaction 2ch4 (g) ⇌c2h2 (g) + 3h2 (g) k = 0.135 at 1615 ∘c. what is kp for the reaction at this temperature?

We can get Kp value from this formula:

Kp = Kc (RT) ^Δn

when Kc = 0.135

and R = 0.08206 L. atm/mol. K

and Δn = total number of moles of products - total number of moles of reactants

= 1+3-2 = 2

T = tempreature in kelvin = 1615 °C+273 = 1888 K

so by substitution:

∴ Kp = 0.135 * (0.08206 * 1888) ^2

= 3240.4
