how do you calculate the equilibrium constant K for a reaction given only the equilibruim pressure for the sample...i thought u needed partial pressures for all substances involved.

They just tell me the eq pressure is 3 atm for the sample and ask for Keq.

Here's the rxn...

NH2COONH4(s) --> 2NH3(g) + CO2(g)

Choices...
A)4
B)1/27
C)4/27
D)27
