Interpretation:
The shape of the graph when equilibrium is established is to be described.
Concept introduction
Equilibrium is that stage where rate of forward and rate of reverse reaction becomes equal.
Answer to Problem 13STP
In the graph, curve A represents the reactants’ concentration-time graph and curve B and C represents the product’s concentration-time graph.
The concentration of reactants is decreasing with respect to time which is represented by curve A and on the other hand, concentration of products will increases with respect to time. At equilibrium rate of forward and reverse reaction becomes equal.
Explanation of Solution
When concentration of reactants and products becomes constant means concentration-time equilibrium occurs.
a. when temperature is changed then both the forward and reverse reactions are affected.
b. change in pressure is also affected the concentration-time reaction graph.
c. change in concentration is also affected the concentration-time graph
d. addition of catalyst would increase both the forward or reveres
For concentration-time graph equilibrium occurs, where concentration of reactants and products are constant. These values need not be equal to each another.
In the graph, curve A represents the reactants’ concentration-time graph and curve B and C represents the product’s concentration-time graph.
The concentration of reactants is decreasing with respect to time which is represented by curve A and on the other hand, concentration of products will increases with respect to time. At equilibrium rate of forward and reverse reaction becomes equal.

For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.arrow_forward
