Question
b) Has the reaction reached equilibrium? c) What is the difference between being kinetically favorable versus thermodynamically favorable? d) What can you conclude about the kinetic/thermodynamic favorability in this reaction? 5. What does "at equilibrium" mean in terms of (a) the rates of the forward and reverse reactions and (b) the concentrations of the reactants and products? involve an increase or decrease inental120s+6 positive? 6. Does the oxidation of glacose, or decrease in entropy? Why? Based on the free-energy equation, would G be negative orExplanation / Answer
b) The reaction has reached to equilibrium, means the rate of forwarding reaction become equal to the rate of backward reaction. It means no further change can be done in the reaction progress without altering the reaction conditions such as quantity of reactants, temperature, and pressure etc.
c) Kinetically favored and thermodynamically favored both are the different terms used for defining the state and progress of the reaction. kinetically favored means rate and mechanism of reaction which tells how fast the starting materials are combining with each other to form the product. It tells about the energy of activation, the rate constant of the reaction, lability and inertness of the compounds.
Thermodynamically favorite stands for the stability of the bonds formed during the reaction and it tells about the equilibrium constant of the reaction and attainment of the equilibrium state during the reaction. it means how much favorable a reaction for the obtaining the state of equilibrium.
d) Kinetic/ thermodynamic favorability of reaction stands for two different things of a reaction. Kinetic favorability tells about the chances of reaction and stability of it which depends on various factors such as nature, stability and reactivity of the species taking part in reaction while thermodynamic favorability of reaction stands for the chances of a reaction for obtaining equilibrium state and how much flavourful conditions are available for reaching the state of equilibrium.
5) At equilibrium
a) the rate of forwarding reaction will always equal to the rate of reverse reaction.
Rf = Rr
where R stands for rate while f and r used for farward and reverse reaction respectively.
b) The concentration of reactant and concentration of products are comparable to each other. It means they are dependent on each other. Slightly change in the concentration of any species will destroy the state of equilibrium.
