Draw energy graph of the reaction where energy reaction is 1kg mol-1 the energy of the product is 50kg mol-1 and the activation is 50kg mol-1.state whether reaction is exothermic o endothermic
To draw the energy graph of a reaction, we need to plot the energy changes that occur during the reaction on the y-axis against the progress of the reaction on the x-axis.
In this case, we have the following information:
- Energy of the reactants (1kg mol-1)
- Energy of the products (50kg mol-1)
- Activation energy (50kg mol-1)
To construct the energy graph, follow these steps:
1. Choose a suitable scale for the y-axis to accommodate the energy values given. Let's say we have a scale from 0 to 60.
2. On the x-axis, draw a straight horizontal line to represent the progress of the reaction from left to right.
3. Mark the energy of the reactants (1kg mol-1) as a point on the y-axis, at the starting point of the reaction.
4. Mark the energy of the products (50kg mol-1) as a point on the y-axis, at the ending point of the reaction.
5. Connect the reactant and product points with a downward sloping line. This represents the overall energy change of the reaction.
6. Finally, mark the activation energy (50kg mol-1) as a barrier on the energy graph. Draw a dashed line at the top of the barrier to represent the activation energy.
Now, to determine whether the reaction is exothermic or endothermic, we need to look at the energy change during the reaction. If the products are at a lower energy level than the reactants, it is an exothermic reaction. If the products are at a higher energy level than the reactants, it is an endothermic reaction.
In this case, the products (50kg mol-1) have a higher energy level than the reactants (1kg mol-1). Therefore, the reaction is endothermic.
Please note that the energy values provided in the question (1kg mol-1, 50kg mol-1) are unusual units for energy (normally given in joules or kilojoules). However, we can still analyze the energy graph and understand the nature of the reaction based on the relative energy levels of the reactants and products.
