Document Summary

Ammonium hydrosulfide decomposes to ammonia and hydrogen sulfide gases. Kp for the decomposition reaction: nh4sh(s) nh3(g) + h2s (g) kcc = 0. 136 (at. To solve: based on the equation, we plug in 0. 136 as the kc, convert the temp to k (500), and use the constant 0. 0821 . Last step before solving is to make sure the exponent is the mol gaseous products minus the mol gaseous reactants, which here is 2-0=2. For the reaction a(g) b(g), the equilibrium mixture at 180 c is a = 2. 0x10-4 m and. B = 8. 0x10-4 m. the molecular scenes below represent four different mixtures for the reaction (a is red; b is blue). 2. in 1 the reaction will progress to the at equilibrium: in 2 the reaction will progress to the right, in 3 the reaction will progress to the right, in 4 the reaction will progress to the right. To solve: everything here is determined by products over reactants!
