Question

At T = 25°C, Kp = 171.3 for the general reaction

2A(g) + B(g) 2C(g) + 2D(g)

Calculate Ke.

Answer 1

2A(g) + B(g) ==>2C(g) + 2D(g)

Kp = Ke(RT)^-∆n

Kp = 171.3

Ke = ?

R = gas constant = 0.0821 Latm/Kmol

T = temp in Kelvin = 25C + 273 = 298K

∆n = change in the number of moles of gas = 4 - 3 = 1

Solving for Ke, we have...

171.3 = Ke (0.0821x 298) = 24.47Ke

Ke = 7.00
