sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. assume the uncatalyzed reaction is endothermic. note: because the sketches are only qualitative, the energies in them dont have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.

Answer

Explanation:

Step1: Understand endothermic reaction

In an endothermic reaction, the energy of products is higher than that of reactants. For the uncatalyzed reaction, draw a curve starting from the reactants' energy level, rising to a peak (activation - energy $E_a$) and then dropping to the products' energy level which is higher than the reactants'.

Step2: Consider the effect of catalyst

A catalyst lowers the activation energy. For the catalyzed reaction, draw a similar curve but with a lower peak (lower $E_a$) while still having the products at a higher energy level than the reactants.

Answer:

Sketch an endothermic reaction energy - diagram for the uncatalyzed reaction with a relatively high activation - energy peak and products at a higher energy level than reactants. Then, sketch a catalyzed reaction energy - diagram with a lower activation - energy peak and products at the same higher energy level compared to reactants as in the uncatalyzed case.
