Final answer:
The value of Kₚ at 227°C for the given reaction is 4.88 X 10⁻⁷.
Step-by-step explanation:
To find the value of Kₚ at 227°C, we can use the equation:
Kₚ = K₆ * (RT)^(∆n)
Where K₆ is the equilibrium constant at 227°C, R is the gas constant, T is the temperature in Kelvin, and ∆n is the change in moles of gas.
In this case, the equation is:
Kₚ = (1.95 X 10⁻³) * (227 + 273)^(1 - 3)
Simplifying this equation gives:
Kₚ = 4.88 X 10⁻⁷
Therefore, the answer is (b) (4.88 X 10⁻⁷).
