The equilibrium constants for the chemical reaction N 2(g) + O 2(g) 2NO(g) are K P = 1.1 × 10 –3 and 3.6 × 10 –3 at 2,200 K and 2,500 K, respectively. Which one of these statements is true?

The answer is "At 2200K, NO(g)'s partial pressure is below 2500K. C.KP by a factor of (RT) is lower than Kc"

Explanation:

In the given question choices were missing so, the correct choice can be defined as follows:

Given:

Reaction equation:

when temperature 2,200 K the value of KP =

when temperature 2,500 K the value of KP =

value of kp=?

In the above formula the value of is defined in the denominator section and the value of is defined in the numerator section that defines the value of KP is increases.so, the temperature of the KP will be KP ∝ (PNO).

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
