Question

What is the standard cell potential for this electrochemical cell? It consists two compartments, labeled C1 and C2. The temperature si 298 K. C1 consists of a copper metal electrode immersed in a 0.30 M copper sulfate solution. C2 consists of a copper metal electrode immersed in a 1.5 M copper sulfate solution. Cu^2+ + 2e^- rightarrow Cu, E^degree_red = +0.34 V a. +0.34 V b. -0.34 c. 0.0 V d. +0.68 V e. More information is needed to decide. For the rate law Rate = k[A][B]^1/2, the partial order with respect to A is, the partial order with respect to B is, and the total order is. Equilibrium con starts for two reactions are known as follows. A + B C K_1 D + E K_2 What is the expression for the equilibrium constant for the reaction in which A and B form one mole each of D and E? If Q for a reaction is greater than k_s the reaction will be. If Q for reaction is less than K_s the reaction will be. If Q for a reaction is equal to K_s the reaction will be. One mole of solid ammonium carbonate (NH_3CO_2NH_2) decomposes to form gaseous ammonia (NH_3) and carton dioxide. Write an expression for the equilibrium constant for this reaction. Consider the reaction of nitrogen and hydrogen gas under standard state conditions to from two moles of ammonia gas (NH_3). Write the initial expression for K_c that would be derived from an ICE table if the concentrations of all species were as follows. [N_2] = 3 M [H_2] = 2 M [NH_3] = 1 M Let s be the number of moles of lead chloride (PbCI_2) that dissolves in water to make exactly 11 of solution. Write the solubility product expression for lead chloride in terms of s. Calculate a value for k_sp given that s = 0.036 M.

Explanation / Answer

Q34

with respect to [A]--> 1 st order; and [B]^1/2 --> 1/2 order... overal = 1+1/2 = 1.5 order

Q35

2A+2B = D+E

2A + 2B = 2C --> K1new = K1^2

2C = D + E --> K2new = -K2

so

total K = (K1)^2 (K2)
