In the graph below, the rate of reaction at point A is the ________ (slowest, fastest, zero) because the amount of reactants particles is ________ (maximum, minimum, zero).
Correct Answer
fastest,faster
maximum,maxExplanation
The rate of reaction at point A is the fastest because the amount of reactant particles is at its maximum. This means that there is a high concentration of reactants available to collide and react, leading to a faster rate of reaction.Rate this question:

In the graph below, the rate of reaction at point C is the ________ (slowest, fastest, zero) because the amount of reactants particles is ________ (maximum, minimum, zero).
Correct Answer
zero,0
zero,0Explanation
The rate of reaction at point C is zero because there are no reactant particles present at that point.Rate this question:
- 17.
What is the energy change for this reaction? ________ KJ/mol
Correct Answer
-97Explanation
The energy change for this reaction is -97 KJ/mol. This means that the reaction releases 97 kilojoules of energy per mole of reactant. The negative sign indicates that the reaction is exothermic, meaning it releases heat energy.Rate this question:
- 18.
What is the bond energy of the C=O bond? ________
Correct Answer
841,+841Explanation
The bond energy of the C=O bond is 841 kJ/mol. This indicates the amount of energy required to break one mole of C=O bonds. The positive sign indicates that this is an endothermic process, meaning energy is absorbed when the bond is broken. The repetition of +841 suggests that this bond energy is consistent and reliable.Rate this question:
- 19.
________
Correct Answer
zinc ethanoate - 20.
________ + ________
Correct Answer
calcium ethanoate,water
calcium ethanoate,waterExplanation
The given answer suggests that the blanks should be filled with "calcium ethanoate" and "water" twice. This implies that the two blanks should be filled with the same options, resulting in a repetition of "calcium ethanoate" and "water" in the final answer.Rate this question:
