Concept Introduction:
Exothermic Reactions:
The chemical reaction in which heat energy is released known as exothermic reaction. The chemical bond will determine whether the reaction is exothermic or endothermic. If the energy released by bond formation is greater than the energy required to break the bond, then the reaction is said to exothermic.
Examples for exothermic reaction:
- Making ice cubes.
- Formation of snow in clouds.
- Condensation of rain from water vapour.
- Rusting iron.
- Burning sugar.

- What is the most common form of kinetic energy that is released from chemical energy in chemical reactions?arrow_forwardWhat is expected to happen to the reaction rate with increasing temperature? (Enzyme kinetics)arrow_forwardA. Will decreasing the amount of energy needed to make an exergonic reaction occur cause the reaction to be more exergonic? Why or why not? B. Will such an energetic alteration change the rate of the reaction? Why or why notarrow_forward
- A chemical reaction has a △G of -14 kcal/mol. Adding an enzyme has been shown to increase the reaction 10-fold. What would be the △G of the reaction when that enzyme is added? A) -1.4 kcal/mol B) -14 kcal/mol C) +14 kcal/mol D) -140 kcal/molarrow_forwardMatch each component of the reaction in the figure with the corresponding relative energy level.arrow_forwardWhich statements concerning free energy change are true?a. Free energy change is a measure of the rate of a reaction.b. Free energy change is a measure of the maximum amountof work available from a reaction.c. Free energy change is a constant for a reaction under anyconditions.d. Free energy change is related to the equilibrium constantfor a specific reaction.e. Free energy change is equal to zero at equilibrium.arrow_forward
- Answer the following question using the reaction coordinàte diagram shown below. 280 240 200 160- 120- 80 40 Time How would the addition of a catalyst affect the reaction? A. The rate of reaction will increase because potential energy of the reactants is increased. B. Catalysts have no effect on reactions. O C. The rate of reaction will decrease because the activation energy is lowered. D. The rate of reaction will increase because the activation energy is decreased. Chp Co Heat content (H) kilojoulesarrow_forwardIn chemical reactions involving two or more substrates, how can mere binding of substrates to an enzyme active site affect the rate of a reaction?arrow_forwardThe concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 36 slices of bread and 51 slices of cheese.arrow_forward
- For this question, use the following reaction and Kc value: 2NH3 (9) * N2(9) + H29) Kc = 3.4 x 104 At equilibrium, what is true about the amount of reactants compared with the amount of products? O A. The amount of reactants are higher than the number of products. B. The number of reactants are lower than the number of products. C. The number of reactants are the same as the number of products. Chparrow_forwardDefine potential energy and kinetic energy and provide two specific examples of each. Explain how one form of energy can be converted into another. Will some energy be lost during this conversion? If so, what form will it take?arrow_forwardEnzymes are biological catalysts that fulfill the following general reaction mechanism: E+S [ES] [EP] E + P Where E is enzyme, S is substrate, and P is product. Briefly describe how an enzyme is able to speed of the rate of a reaction:arrow_forward
