For the pair of species given:
1. Lithium (E° = -3.05 V) and silver (E° = 0.80 V)
2. Aluminum (E° = -1.66 V) and zinc (E° = -0.76 V)
  1. Write balanced half-reactions and the overall spontaneous reaction.
  2. Diagram the cell. Be a specific as possible including labeling electrodes with their charges and names (anode and cathode), showing the direction of electron flow in the circuit and showing the direction of cation and anion flow in the salt bridge.
  3. Calculate the cell potential for the overall reaction.
  4. Calculate the Gibbs free energy for the overall reaction.
  5. Write the standard cell notation for the overall reaction.
  6. Calculate K_eq for the spontaneous reaction.

Expert Solution

Greater is the standard reduction potential of the metal electrode reduction takes place on that electrode. While lower is Standard reduction potential, higher will be its standard oxidation potential, thus oxidation takes place on that electrode.

a. Oxidation of Li takes place on anode . While Reduction of Ag+ takes place on cathode.

Cell potential = E° cathode - E° anode

The Gibbs free energy = - n F E° cell

The equilibrium constant = Keq

Log(keq) = 16.92 n E° cell

Or delta G = - 2.303 n R T log(Keq)

Given a graph G = (V,E), the source-sink pair (s,t) and capacity of edges {C_e ≥ 0 | e ∈ E}, design a polynomial-time algorithm to find a set of edges S, such that for every edge e ∈ S, increasing C_e will lead to an increase of max-flow value between s and t. Show the correctness of your algorithm.

Determine, for a given graph G =V,E and a positive integer m ≤ |V |, whether G contains a clique of size m or more. (A clique of size k in a graph is its complete subgraph of k vertices.)

You are given an undirected graph G = ( V, E ) in which the edge weights are highly restricted. In particular, each edge has a positive integer weight from 1 to W, where W is a constant (independent of the number of edges or vertices). Show that it is possible to compute the single-source shortest paths in such a graph in O(E+V) time.

In chickens, silver and gold feathering is determined by a single pair of alleles as is slow and rapid feather development. True-breeding males that were silver, slow feathered were crossed with true-breeding females that were gold, fast feathered. All F1 were silver, slow feathered. The F2 phenotypes were as follows: 300 male progeny were silver, slow feathered; 120 females were silver, slow feathered; 123 females were gold, rapid feathered 35 females were silver, rapid feathered; and 32 females were gold,...
