Question

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)+H2SO4 (aq) ZnSO4 (aq)+H2(g) Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels by adding 143.6 g of solid zinc and 71. 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 AM vessel volume temperature initial rate of reaction 4.0 L 15.0 °C ? B. 2.0 L 16.0 °C ? с 2.0 L 15.0 °C ? D 4.0 L 14.0 °C ? Х ?

Answer 1

According to arhenius equation

K=A*e^{​​​​-Ea/RT}

More is temperature more is value of k and as a result more value of rate of reaction

B=1

D is 4

In A and C temperature is same but when Volume is high rate is low

A is3

C is 2
