Calculate K, for the reaction,CH, (g) + H2 (g)aio i#-100 kJ ınol-1 at 25°C.19C,H, (g)

Answer»

Thefree energychange of the reaction in any state, ΔG (when equilibrium has not been attained) is related to the standardfree energychange of the reaction, ΔG0(which is equal to thedifferenceinfree energiesof formation of the products and reactants both in their standard states) according to the equation.

use value of R as 8.3145temp: 273+25 = 298Kand the value of free gibb's energy given

and using the equation given above, solve the question.
