If the equilibrium constant for the reaction A 2B C 5/2 D has a value of 4.0, what is the value of the equilibrium constant for the reaction 2C 5D 2A 4B at the same temperature

Explanation:

Hello!

In this case, since the given reaction is:

Whereas the equilibrium constant is:

However, the new target reaction reverses and doubles the initial reaction to obtain:

Whereas the equilibrium constant is:

Which suggest the following relationship between the equilibrium constants:

So we plug in to obtain:

Best regards!

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

i think it's letter a.
