Consider the following reaction: 2 NO(g) + Br2(g) ⇄ 2 NOBr(g) Kp = 27 at 25°C What is the value of Kc at 25°C?
Paul [167]

Answer:

The value of Kc is 660 (Option E) is correct

Explanation:

Step 1: Data given

Kp = 27

Temperature = 25.0 °C

Step 2: The balanced equation

2 NO(g) + Br2(g) ⇄ 2 NOBr(g)

Step 3: Calculate Kc

Kp = Kc * (RT)^Δn

⇒ with Kp = 27

⇒ with Kc = TO BE DETERMINED

⇒ with R = the gas constant = 0.08206 L*atm/mol*K

⇒ with T = The temperature = 25 °C = 298 K

⇒ Δn = the difference in moles = -1

 

27 = Kc * (0.08206*298)^-1

Kc = 660

The value of Kc is 660 (Option E) is correct

Clasifica según sea: solución, coloide o suspensión.
makkiz [27]

Answer:

Sal, cobre, aluminio, anillo de oro puro Oxígeno ------ suspensión.

Cerveza, carbonato de sodio, oxígeno, carbono y helio ------ solución.

Explicación:

Sal, Cobre, Aluminio, Anillo de oro puro Oxígeno son los ejemplos de suspensión porque permanecen suspendidos en la solución mientras que por otro lado, Cerveza, Carbonato de sodio, Oxígeno, Carbono y helio son los ejemplos de solución porque formaron una mezcla homogénea en la que ambas soluciones no se pueden diferenciar entre sí pero en suspensión sí se pueden diferenciar.
