To draw a reaction profile for the reaction 2N2 + O2 + heat → 2N2O, including proper labels for each axis, reactants, products, activation energy, and transition state, follow the steps below:
Step 1: Create the Y-axis (Energy axis)
- Label the Y-axis as "Energy" or "Gibbs Free Energy" (ΔG).
- This axis represents the energy of the system throughout the reaction process.
Step 2: Identify the initial energy level of the reactants
- Draw a line on the Y-axis at the energy level of the reactants (2N2 + O2).
- Label this line as "Reactants."
Step 3: Identify the final energy level of the products
- Draw a line on the Y-axis at the energy level of the products (2N2O).
- Label this line as "Products."
Step 4: Set the X-axis (Reaction progress axis)
- Label the X-axis as "Reaction Progress" or "Reaction Coordinate."
- This axis represents the progress of the reaction from the reactants to the products.
Step 5: Designate the reaction pathway
- Draw a curvy line connecting the reactants (starting point) and the products (end point) on the X-axis.
- This line represents the reaction pathway from the initial state to the final state.
Step 6: Mark the activation energy
- Find the highest point on the reaction pathway.
- Draw a peak or hill representing the activation energy barrier at this point on the curve.
- Label it as "Activation Energy" (Ea).
Step 7: Identify the transition state
- On the peak representing the activation energy, draw a dashed line to indicate the transition state.
- The transition state is the highest energy point on the reaction pathway and is a fleeting species formed during the reaction.
Optional: Include any intermediate(s)
- If there are any intermediates formed during the reaction, draw additional lines or peaks to represent them on the reaction pathway.
- Label these intermediates if necessary.
Overall, the reaction profile should include proper labels for the Y-axis (Energy), X-axis (Reaction Progress), reactants, products, activation energy (Ea), and transition state.
