In general, as activation energy increases, reaction rate ________. goes down if the reaction is exothermic goes down if the rea
vova2212 [387]

Answer:

goes down regardless of whether the reaction is exothermic or endothermic

Explanation:

The activation energy is the minimum energy the reactants in a chemical reaction will have to reach in order to be transformed into products.

Hence, the higher the activation energy of a reaction, the lower the reaction rate and the lower the activation energy of a reaction, the higher the reaction rate.

Activation energy is independent of whether a reaction is exothermic or endothermic.

<em>Therefore, as activation energy increases, reaction rate goes down irrespective of whether is is exothermic or otherwise.</em>

A proposed mechanism for the reaction of NO2 and CO is
Novosadov [1.4K]

Answer:

a.

1. NO2(g): Reactant.

2. CO(g): Reactant.

3. NO3(g): Intermediate.

4. CO2(g): Product.

5. NO(g): Product.

b. See attached picture.

Explanation:

Hello,

a. In this case, given the reactions, we can identify each species as:

1. NO2(g): Reactant because it remains at the left side in the overall reaction.

2. CO(g): Reactant because it remains at the left side in the overall reaction.

3. NO3(g): Intermediate because it is a product in the step 1 and a reactant in step 2, for that reason it is not present in the overall reaction.

4. CO2(g): Product because it remains at the right side in the overall reaction.

5. NO(g): Product because it remains at the right side in the overall reaction.

b. In this case, given that the first step is slow and endothermic, it has a high activation energy and the products will have more energy than the reactants, for that reason the final energy is above the initial point. Moreover, since the second step is fast and exothermic, it has a low activation energy and the products will have less energy than the reactants, for that reason, the reaction coordinate diagram is shown on the attached file.

Regards.

If the only chemical you can find is labeled with the wrong concentration:_______
Softa [21]

Answer:inform the lab instructor and get instructions

Explanation:

If you come across a chemical in the laboratory which has been wrongly labelled, do not be quick to dilute it or take any further action. The laboratory instructor who may have prepared the reagent himself or has better knowledge about the reagent should be contacted immediately so that he/she can give you instructions about what to do with the wrongly labelled reagent.
