Question

coal gasification produces an easily - transportable, clean - burning combination of carbon monoxide and hydrogen from coal by reacting it with steam, like this:
c(s)+h₂o(g)→co(g)+h₂(g)
suppose an engineer decides to study the rate of this reaction. he prepares four reaction vessels with 179.3 g of solid carbon and 12.6 g of steam each. 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.

Explanation:

Step1: Understand the relationship between temperature and reaction rate

In general, for most chemical reactions, as the temperature increases, the initial rate of the reaction also increases. This is because higher temperatures provide more kinetic energy to the reactant molecules, leading to more frequent and energetic collisions, which are necessary for the reaction to occur.

Step2: Compare the temperatures of the vessels

Vessel A has a temperature of \(390.^{\circ}C\), vessel B has \(360.^{\circ}C\), vessel C has \(380.^{\circ}C\), and vessel D has \(370.^{\circ}C\). Arranging the temperatures in decreasing order: \(390.^{\circ}C>380.^{\circ}C > 370.^{\circ}C>360.^{\circ}C\)

Answer:

A (with the highest temperature of \(390.^{\circ}C\)) will have the highest initial reaction rate. Then comes C (\(380.^{\circ}C\)), followed by D (\(370.^{\circ}C\)), and B (\(360.^{\circ}C\)) has the lowest initial reaction rate among the four vessels. So the order is A - 1, C - 2, D - 3, B - 4.
