Question

Determine the value of Kc for the reaction: H2 (g) + O2 (g) ⇌ H2O2 (g), given that its Kp at 640 K is equal to 2.3x10^6

Answer 1

WE KNOW Kp = (Kc*RT)RAISED TO DELTA ng

here delta ng = -1

T = 640

R = 0.0821

Kp = 2.3*10^6

putting values we get,

Kc = 2.3*10^6*0.0821*640

Kc = 120*10^6
