Consider this equilibrium: 3fe(s) + 4h2o(l) fe3o4(s) + 4h2(g). what is the keq expression for this equilibrium?

Remember that in a Keq expression, you do products over reactants, and these can only be compounds in the gaseous or aqueous state.

for this equation

Keq= [H2]^4

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .

It has to be b i hope this
