i nee help in this question any help would be appreciated the question is
1.Given the reaction:
A(g) + 2 B(g) ---> C(g) + D(g) ��H = -40 KJ,
a. If the activation energy in the forward direction is 80KJ, plot the PE
diagram.
b. Plot a KE distribution diagram in which about 10% of the molecules will
meet or exceed the activation energy
Thank you
To answer your question, I would need to explain the steps to create the PE diagram and KE distribution diagram. Here's how you can approach it:
a. Plotting the PE diagram:
1. Start by drawing a horizontal line to represent the potential energy (PE) axis.
2. Label the left side of the line as the initial state and the right side as the final state.
3. Identify the reactants (A and B) on the left side and place them at a higher energy level than the products (C and D) on the right side.
4. Draw curved lines connecting the initial and final states, representing the energy changes during the reaction.
5. Label the reaction coordinate (x-axis) along the curved lines, showing the progress of the reaction from the initial to the final state.
6. Add arrows along the curved lines to indicate the activation energy (EA) for the forward reaction, which is given as 80 KJ in this case.
7. Finally, label the energy change (∆H), which is given as -40 KJ.
b. Plotting the KE distribution diagram:
1. Start by drawing a vertical line to represent the kinetic energy (KE) axis.
2. Label the bottom of the line as the minimum KE required for the reaction to occur (activation energy).
3. Divide the KE axis into intervals (e.g., 10% intervals).
4. Starting at the activation energy level, draw rectangles representing the percentage of molecules with that or higher KE.
5. Proceed upwards, adding rectangles for each interval until you reach 100%.
6. At each interval, label the percentage of molecules with that KE or higher.
7. In this case, you want to plot the KE distribution diagram in which about 10% of the molecules will meet or exceed the activation energy (80 KJ).
Please note that creating accurate diagrams requires attention to scale and sufficient space to represent the different energy levels. It might be helpful to use graphing software or drawing tools to assist you.
I hope this explanation helps you create the PE diagram and KE distribution diagram for the given reaction. If you have any further questions, feel free to ask!
