If 2.50g of CuSO4 is dissolved in 8.95 x 10^2 mL of 0.300 M NH3, calculate the concentrations of the following species at equilibrium: Cu^2+, NH3, Cu(NH3)4^2. I tried to solve and came up with the following-

Cu^2+ = 1.1149x10^-13 (Which was all wrong except for the 10^-13)

NH3 = .230 (Which was correct)

Cu(NH3)4^2+ = 0.069720 (Which was wrong)

Can someone please show me where I am going wrong.

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
