What information does a potential energy diagram reveal about a reaction?
It shows whether the reaction is exothermic or endothermic.
What information does the potential energy diagram reveal about reaction?
It shows whether the reaction is exothermic or endothermic.
How do you know if an enthalpy change diagram is endothermic or exothermic?
In an endothermic reaction, the products have higher enthalpy than the reactants, leading to a positive overall change in enthalpy. In contrast, in an exothermic reaction, the products have lower enthalpy than the reactants, resulting in a negative overall change in enthalpy. This information can be determined by looking at the direction in which the energy levels are changing on the enthalpy change diagram.
Is the transition state the slowest step in a reaction mechanism?
The transition state is not a step in a reaction mechanism; it is a high-energy state that exists at the peak of the reaction potential energy diagram. The slowest step in a reaction mechanism is often referred to as the rate-determining step, which has the highest activation energy and determines the overall rate of the reaction.
How do you draw a Potential Energy Diagram?
To draw a potential energy diagram, you typically plot the potential energy on the y-axis and the reaction coordinate on the x-axis. Identify the initial and final states of the reaction, determine the energy changes at each stage, and sketch the curve connecting the energy levels. Peaks represent transition states, while valleys indicate stable intermediates or products.
