Question

which statement about the following equilibrium is correct?
2SO2 +O2 -> 2SO3 ΔH= -395 kJ/m

A. The value of Kp falls with rise in temperature
B. The value of Kp falls with increase in pressure
C. The value of Kp is equal to Kc
D. The value of Kp remains constant with rise in temperature

Right answer is B. ​

Answer 1

Answer:

Equilibrium constants are changed if you change the temperature of the system. Kc or Kp are constant at constant temperature, but they vary as the temperature changes. You can see that as the temperature increases, the value of Kp falls.

Answer 2

Concept introduction:

Chemical equilibrium refers to the situation in a chemical process where both the reactants and products are at concentrations that have no further tendency to vary over time, preventing any discernible change in the system's characteristics.

Explanation:

We have to choose the correct statement about the following equilibrium.

An equilibrium equation has been given to us.

$2SO_2 +O_2 - > 2SO_3 \Delta H= -395 kJ/m$

Equilibrium constants are changed if you change the temperature of the system. Kc or Kp are constant at constant temperature, but they vary as the temperature changes. You can see that as the temperature increases, the value of Kp falls.

Final answer:

The final answer of the question is A. The value of Kp falls with rise in temperature.
