Problem

At the start of a certain reaction, only reactants are present; no products have been formed. What is the value of Qc at this point in the reaction?

Solution

We are being asked to determine the value of the reaction quotient, Qc at the start of a certain reaction, when only reactants are present; no products have been formed.


Recall that the reaction quotient, Q, can be calculated like an equilibrium constant with the formula shown below:


Q=productsreactants


Since there are no products formed, this means that:
