Fe3+ reacts with bromine ion (Br-) and one of the product is Fe+2 . Complete the following reaction and find the sum of all coefficients (including one) Fe+3(aq) + Br-(aq) -->
In Chem 113, we saw that the heat associated with a chemical reaction could be determined in one step, or as the sum of two steps, as long as the two steps resulted in the same overall reaction. (Hess' Law). Consider a reaction which occurs in the two steps shown below. What is the overall reaction that these two steps are equivalent to? Step 1: H2O2(aq) + I-1(aq) --> H2O + OI-1(aq) Step 2: H2O2(aq) + OI-1(aq) --> H2O + O2(g) + I-1(aq) a. 2 H2O2(aq) + 2 OI-1(aq) --> 2 H2(g) + 3 O2(g) + 2 I-1(aq) b. 2 H2O2(aq) --> 2 H2O + O2(g) c.

The conversion of natural gas, which is mostly methane,into products that contain two or more carbon atoms, suchas ethane (C2H6), is a very important industrial chemicalprocess. In principle, methane can be converted into ethaneand hydrogen: 2 CH4(g)----->C2H6(g) + H2(g) In practice, this reaction is carried out in the presence ofoxygen: 2 CH4(g) + 12O2(g)---->C2H6(g) + H2O(g) (a) Calculate K for these reactionsat 25 °C and 500 °C.

(c) Explain how the precedingreactions are an example of driving a nonspontaneousreaction, (d) The reaction of CH4 and O2 to form C2H6 and H2O must be carried out carefully to avoid a competingreaction.
