( the reaction 2 HgO(s)--> 2 Hg(1) + O2(g) we measure the evolution of gas to determine the rate of reaction. At the beginning of the reaction (at 0 minutes), 0.020 L of O2 is present. After 15 minutes the volume of O2 is 0.35 L. What is the rate of reaction in L/min? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

Thiosulfate ions are oxidized by iodine according to the reaction below:2 S2O 33- (aq) + I2 (aq) → S 4O 62- (aq) + 2I -(aq)If 0.0080 mol of S2 O32- is consumed in 1.0 L of solution every second, what isconsumption rate of iodine?

In the laboratory, hydrogen gas of good purity can most easily be obtained by the reaction of a strong acid, like sulfuric acid, on a reactive metal, such as zinc: Zn(s)+H,SO,(aq) ZnSO,(aq)+H, (g) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels by adding 160.9 g of solid zinc and 83. mL of 5.0 M sulfuric acid solution to each, and then filling the remainder of the vessel with distilled water. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on. alo Ar initial rate of vessel volume temperature reaction A 1.0 L 14.0 °C В 4.0 L 14.0 °C ? 2.0 L 14.0 °C 8.0 L 14.0 °C v ? 1 (highest) 2 4 (lowest) >
