# In a reaction mixture containing only reactants, what is the value of q?

Chemists use a quantity called the reaction Quotient to assess if a system has achieved equilibrium ( Q ). The reaction Quotient expression is identical to the equilibrium constant expression, with the exception that Q may be calculated from a set of values taken at any moment during the reaction of any combination of reactants and products, regardless of whether the system is at equilibrium.

## in a reaction mixture containing only reactants, what is the value of q?

• Even in reactions that convert reactants to products in an instantaneous manner, a defined quantity of reactant concentration persists.

Following 100% conversion to products, you obtain NaCl and H2O after a titration of aqueous NaOH solution against aqueous HCl solution. The pH of the solution is 7.0, which indicates that it is NEUTRAL.

A pH of 7 indicates that the concentrations of OH- and H3O+ in equilibrium with NaCl and H2O are 10-7 M and 10-7 M, respectively. Even if the reactant concentration is smaller than the analytical equipment’s detection limit, finding a reaction mixture with no reactants is very challenging.

Even with Cobalt-60 or comparable radioactive decay, residual radioactivity TENDS TO INFINITE, but never approaches zero. As a result, Q is always definable and may go to a huge number, but it is never undefined (i.e. no division by zero).

• At any given moment, the reaction quotient is the actual ratio of products to reactants. The formula is the same as it is for k. Q =[reactants]/[products]. Q = k when the reaction is at equilibrium. Q cannot be used when there are no products since it divides by zero.

## F.A.Q: in a reaction mixture containing only reactants, what is the value of q?

### How can you figure out what a reaction’s Q is?

Multiply the activities for the species of the products and divide by the activities of the reagents to determine the reaction quotient Q, elevating each of these values to the power of the relevant stoichiometric coefficient.

### Is it possible for the response quotient to be zero?

The individual components in the equilibrium expression might have any value (even zero); the reaction quotient Q is the value of the equilibrium expression itself.

### Is it possible for Q to be infinite?

As a result, when all reactants and no products are present, Q = zero. When there are no more reactants and just products remaining, we have 0 in the denominator, which gives us an infinite Q value. As a result, we have all products when Q = infinity.
