41. 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).

Explanation

At point A in the graph, the rate of reaction is the fastest because it has the steepest slope, indicating a rapid change in the concentration of reactants over time. This suggests that the reaction is occurring at a high rate. Additionally, the amount of reactant particles at point A is at its maximum, as indicated by the highest point on the graph. This means that there are a large number of reactant particles available to participate in the reaction, further supporting the idea that the reaction is happening at a fast rate.

Submit
42. 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).

Explanation

The rate of reaction at point C is zero because there are no reactant particles present at that point. As a result, no reaction can occur, leading to a rate of zero.

Submit
43. What is the energy change for this reaction? _____ KJ/mol

Explanation

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.

Submit
44. Match the following
Submit
45. What is the bond energy of the C=O bond? _____

Explanation

The bond energy of the C=O bond is 841 kJ/mol. This means that it requires 841 kJ of energy to break one mole of C=O bonds. The +841 indicates that this value is for the reverse reaction, where the C=O bond is formed and releases 841 kJ of energy.
