equal to the

number of electrons

Explanation: this is what I learned in honors chemistry last year, and the number of neutrons and protons are the equal amount of electrons present.

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
