Q1
Reaction quotient expresses the relation between the relative amount of products and reactants in an given instant.
Q2
QQ3
Kc helps in calculating the final concentration at equilibrium for a reaction while Qc helps us understand the relative amounts of products and reactant in a reaction in a given instant

1] A reaction quotient is the proportion of the concentrations of reactants and products within a system. This can be measured at all times in the reactionfrom the initial stage to the very end.

2] Kc = 1.7*10(2) @ 500K
Q = (8.00)^2/[(1.00)^3*(1.50)^]
Q = 42.7
Q
3] Q is the proportion of reaction to products at any given point in the reaction but Kc can be measured only at equilibrium.

1) The reaction quotient Q measures the relative amounts of reactants and products at a point of time. This is expressed with non-equilibrium concentrations.
2) K= [(NH₃)² ]/ [(N₂ ) * (H₂)³]
= [(8.00)² ]/ [(1.50 ) * (1.00)³]
=42.7
As the Qc there are more reactants than products thus to decrease the amount of reactants, the reaction will shift to the right and produce more products.
3) Kc the concentration of reactants and products are at equilibrium. whereas, Q is measured at any point of time.

1. Reaction quotient measures the relative amounts of reactants and products at a point in time.

2. Q = 42.7
Kc = 170
Q < Kc
Hence the reaction mixture is not in equilibrium. The direction in which the reaction will progress is towards the products (towards the right)

3. Kc is calculated using the equilibrium concentrations of reactants and products, and Q is calculated using concentrations of reactants and products at any given point in time.

1) the reaction quotient expresses the relative ratio of products to reactants at a given instance

2) Q < Kc, the reactants are more than the products therefore the reaction shifts to the right to convert more reactants to products to achieve equilibrium.

3) Kc is the equilibrium constant which is calculated using the values for concentration at equilibrium while the Qc, the reaction quotient does not specify the instance at which the concentrations are calculated.

1) the reaction quotient, Q, expresses the relative ratio expresses the relative ratio of product to reactant at a given instant.
2) Q3) Kc is Equilibrium constant at a fixed temperature can be calculated using values for conc. at equilibrium at Qc
