O GASES, LIQUIDS AND SOLIDS -Understanding conceptual components ofthe enthalpy of solution A small amount of acetonitrile (CH,CN is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH,CN HO solution Use these sketches to answer the questions in the table below The enthalpy of solution Hsoln is negative when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. O absorbeod O released O neither absorbed nor released Would heat be absorbed or released if the system moved from Stage A to B?Explanation / Answer
Answer :
In this system the Enthapy of the reaction is negative. That means the reaction is the Exothermic reaction .
In the Exothermic reactions the heat releases.
The H- bonds forms between the Acetonitrile and water. It favors the system to move from A to B.
