Question
**Chemical Equilibrium Problem:**

**Reaction:** 
\[ 1 \, \text{A} + 1 \, \text{B} \rightleftharpoons 3 \, \text{C} \]

**Given:**
- The initial concentration of \([\text{A}]\) is 1.20 M.
- The initial concentration of \([\text{B}]\) is 1.50 M.
- The equilibrium constant (\(K_c\)) is 0.0000076.

**Problem:**
What is the concentration of \([\text{C}]\) at equilibrium?

**Note:** You may assume the 5% rule is valid for this calculation. 

In solving this problem, utilize the equilibrium expression derived from the balanced chemical equation and apply the 5% rule to simplify your calculations if applicable.

Expert Solution
Step 1

While calculating the concentrations of the individual components in an equilibrium, the amount of reactant dissociated, say ‘x’ by a time, ‘t’, then the subtracting x from the value of initial concentration is not necessary if, x is less than or equal to 5%.
