Interpretation:
The
Concept introduction:
- Rate of reaction is typically defined as how concentration changes with respect to time.
- Factors affecting the rate of reaction are:
Temperature: Due to high temperature, the movement of atoms become faster and thus, resulting in increasing the chances of colliding and reacting together.
Concentration: Higher the number of atoms, greater is the chance of colliding and reacting together.
Particle size: The large size of the particles will not react as most atoms are stuck inside whereas a large number of small particles has higher chances of colliding and reacting together.
To explain: The rate of reaction definition and the reason for the quicker growth of mold on bread at room temperature compared to the refrigerator.

- use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.arrow_forwardHow would you express the rate of the chemical reaction AB based on the concentration of Reactant A? Howwould that rate compare with the reaction rate based onthe Product B?arrow_forwardWhy awe elementary reactions involving three or more reactants very uncommon?arrow_forward
- Define these terms: (a) unimolecular reaction (b) bimolecular reaction (c) elementary reaction (d) overall reactionarrow_forwardBased on the diagram in Exercise 12.83, which of the reactions has the fastest rate? Which has the slowest rate?arrow_forwardThe rate law for a reaction can be determined only from experiment and not from the balanced equation. Two experimental procedures were outlined in Chapter 12. What are these two procedures? Explain how each method is used to determine rate laws.arrow_forward
- Consider the hypothetical reaction A+B+2C2D+3E In a study of this reaction three experiments were run at the same temperature. The rate is defined as [B]/t. Experiment 1: [A]0 = 2.0 M [B]0 = 1.0 103 M [C]0 = 1.0 M [B] (mol/L) Time(s) 2.7 104 1.0 105 1.6 104 2.0 105 1.1 104 3.0 105 8.5 105 4.0 105 6.9 105 5.0 105 5.8 105 6.0 105 Experiment 2: [A]0 = 1.0 102M [B]0 = 3.0 M [C]0 = 1.0 M [A] (mol/L) Time(s) 8.9 103 1.0 7.1 103 3.0 5.5 103 5.0 3.8 103 8.0 2.9 103 10.0 2.0 103 13.0 Experiment 3: [A]0 = 10.0 M [B]0 = 5.0 M [C]0 = 5.0 101M [C] (mol/L) Time(s) 0.43 1.0 102 0.36 2.0 102 0.29 3.0 102 0.22 4.0 102 0.15 5.0 102 0.08 6.0 102 Write the rate law for this reaction, and calculate the value of the rate constant.arrow_forwardHow does an increase in temperature affect rate of reaction? Explain this effect in terms of the collision theory of the reaction rate.arrow_forwardA friend of yours states, A balanced equation tells us how chemicals interact. Therefore, we can determine the rate law directly from the balanced equations. What do you tell your friend?arrow_forward
