A common reaction used to study reaction kinetics is the dissolution of sodium thiosulfate in hydrochloric acid. This process is monitored by cloudiness in the container for the following reaction: 2HCl(aq) + Na2S2O3(aq) → S(s) + SO2(g) + 2NaCl(aq) + H2O(l)

Requried:
a. Write 3 - 4 sentences to describe the difference between the chemical reaction if it were set up so that test tubes containing a 0.1 M HCl solution and a 0.1 M Na2S2O3 solution were incubated on ice or in a 70°C water bath before the reaction began. Be sure to include observations and the effect on the rate constant.
b. Suppose 1 M Na2S2O3 increased the rate of the reaction but 1 M HCl did not affect the reaction rate. Write 3 - 4 sentences to describe what these results tell about the rate law and the mechanism for the reaction. Explainyour reasoning.

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
