3H2(g) + N2(g) 2NH3(g) When the above reaction reaches equilibrium at 273 K the partial pressures for each gas are:
PH2 = 0.100 atm
PN2 = 0.050 atm
PNH3 = 1.50 atm
Calculate the equilibrium constant, Kp, for the reaction at 273 K.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
