Consider the decomposition of ammonium hydrogen sulfide: NH4HS(s) <--> NH3(g) + H2S(g)...In a sealed flask at 25 degrees C are 10.0g of NH4HS, ammonia with a partial pressure of 0.692 atm, and H2S with a partial pressure of 0.0532atm. When equilibrium is established, it is found that the partial pressure of ammonia has increase by 12.4%. Calculate K for the decomposition of NH4HS at 25 degrees C.
Study of a first-order reaction, In the study of a first-order reaction, A--->B, it is found that A/Ao=0.125 after one hour. The system initially consisted of 0.20 mole of a gaseous A at 25 degrees C and 1 atm
