Can you explain the answer of this question below:Which of the followi...
Statements A and C are correct. An irreversible reaction goes to completion, meaning all reactants are converted to products. At equilibrium in a reversible reaction, the rates of the forward and backward reactions become equal. However, statement B is incorrect because reversible reactions do not always go to completion in a closed vessel; they can establish an equilibrium with both reactants and products present. Additionally, statement D is false, as the rate of the forward reaction is initially greater than the backward reaction due to the limited amount of products available at the start.

Can you explain the answer of this question below:Which of the followi...
**A: An irreversible reaction goes to almost completion.**

- An irreversible reaction is a reaction that proceeds in one direction only and cannot be reversed.
- In an irreversible reaction, the reactants are converted into products and the reaction goes to completion.
- This means that all the reactants are converted into products and no reactants are left at the end of the reaction.
- The reaction continues until the limiting reactant is completely consumed.
- Therefore, statement A is correct.

**C: At equilibrium, the rate of forward reaction becomes equal to that of backward reaction.**

- An equilibrium is a state in a chemical reaction where the rate of the forward reaction is equal to the rate of the backward reaction.
- At equilibrium, the concentrations of the reactants and products remain constant over time.
- The forward and backward reactions are still occurring, but at equal rates, resulting in no net change in the concentrations of the reactants and products.
- This dynamic balance between the forward and backward reactions is represented by the equilibrium constant (K).
- The equilibrium constant (K) is the ratio of the concentrations of the products to the concentrations of the reactants, each raised to the power of their respective stoichiometric coefficients.
- At equilibrium, the rate of the forward reaction becomes equal to that of the backward reaction, as the concentrations of the reactants and products reach a steady state.
- Therefore, statement C is correct.

In conclusion, statement A is correct because an irreversible reaction goes to almost completion, and statement C is correct because at equilibrium, the rate of the forward reaction becomes equal to that of the backward reaction.

As irreversible reaction is carried out in an open vessel it goes to almost completion and the product can be used to almost completely so it goes to completion .And at equilibrium the rate of forward and backward reaction is equal due to the reaction has gained max stability and so it does not need to equalise the reactant and product

Similar JEE Doubts

A gaseous sample is generally allowed to do only expansion/compression type of work against its surroundings. The work done in case of an irreversible expansion (in the intermediate stages, of expansion/compression the states of gases are not define d). The work done can be calculated usingdW = NextdVwhile in case of reversible process the work done can be calculated using dw = PdV where P is pressure of gas at some intermediate stages. Like for an isothermal reversible process.Since d w = P d V so magnitude of worked one can also be calculated by, calculating the area under the PV curve of the reversible process in PV diagram.Q.Two samples (initially under same states) of an ideal gas are first allowed to expand to double their volume using irreversible isothermal expansion against constant external pressure, then samples are returned back to their original volume first by reversible adiabatic process and second by reversible process having equation PV2 = constant then
