Chemistry help please! equilibrium?
Ammonium carbamate (NH2COONH4) is a salt of carbamic acid that is found in the blood and urine of animals. At 250.0 °C, Kc = 1.58×10-8 for the following equilibrium:
NH2COONH4(s) <=> 2NH3(g) + CO2(g)
If 2.68 g NH2COONH4 is introduced into a 0.500 L evacuated container, what is the total pressure inside the container at equilibrium?
Answer:
1. Appreciate that Kc = [NH3]squared x [CO2]
2. So Kc = (n/V) cubed. You are given V, so solve for n.
3. Total moles of gas = 3n. p = 3nRT/VLimestone on acidity?
