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

Kp is the equilibrium constant.The Kp value for the given reaction is 3240.4.

2 moles of methane form 1 mole of acetylene and one mole of Hydrogen.

Kp is the equilibrium constant. It is calculated from the partial pressures of a reaction equation. It express the relationship between product pressures and reactant pressures.

Formula of Kp,

Where,

Kp - Equilibrium constant based on pressure

Kc - Equilibrium constant based on concentration = 0.135

R - gas constant  = 0.08206 L.atm/mol.K

- moles of gaseous products = 1+3-2 = 2

T - temperature in kelvin = 1615 °C+273 = 1888 K

Put the values in the formula

The Kp value for the given reaction is 3240.4.
