(a)
Interpretation:
For the given reaction, balance equation using chemical formula has to be given. Also the reaction has to be identified as unimolecular or bimolecular.
Concept Introduction:
If the reaction contains only one reactant then it is unimolecular and elementary reaction.
In a bimolecular reaction there will be exactly two reactants, they may be either same or different. If a reaction contains more than two reactants then it is not elementary.

- Drawing thé reaction energy dlagrum 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 don't 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.

The lower the rate of a reaction the longer it takes to reach completion. The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step. Catalysts decrease reaction rates. Reaction rates increase as concentrations of homogeneous catalysts increase. The fastest step in a reaction is called the rate-determining step. Solid catalysts do not affect reaction rates. As a reaction progresses its rate goes up.arrow_forward

Identify the statements that explain the correlation between the increase in temperature and the increase in reaction rate. More atom-atom stretching and bending within the molecules occurs at higher temperatures, which creates more reactive molecular configurations. Added heat decreases the activation energy of a reaction and has a similar effect as adding a catalyst. ✔ Molecules at higher temperatures have greater kinetic energy, which results in more frequent and higher energy collisions. An increased temperature improves the reaction pathway by decreasing the energy difference between reactants and products.arrow_forwardis chemical reactions and reaction rate the same?arrow_forward
- Typical Chemical Potential Energy (PE) Diagram for an Exothermic Reaction A catalyst provides an alternate pathway for a reaction to occur. The alternate pathway has a lower activation energy (AE), meaning that the reactant molecules do not need to collide with as much energy in order for a reaction to occur, so more collisions result in a reaction, so the reaction rate is faster. Chemical Potential Energy (Enthalpy) Note that adding a catalyst does not change the amount of energy released (AH) for the reaction.
