Cevap

To find the value of Kp, we can use the relationship between Kc and Kp:Kp = Kc * (RT)^(Δn)where R is the gas constant, T is the temperature in Kelvin, and Δn is the change in the number of moles of gas.First, let's calculate the change in the number of moles of gas (Δn):Δn = (2 moles of NO2) - (2 moles of NO + 1 mole of O2) = 2 - 3 = -1Now, we can plug in the values into the equation:Kp = Kc * (RT)^(Δn)Kp = 5.84 x 10^5 * (0.0821 * 513.15)^(-1)Kp = 5.84 x 10^5 * (0.0821 * 513.15)^(-1)Kp = 5.84 x 10^5 * (0.0421)^(-1)Kp = 5.84 x 10^5 * 23.6Kp = 1.39 x^4Therefore, the correct answer is B) .
