Balance the equation and write the reaction-quotient expression, Qc.
U(s) + F2 (g) <----> UF6 (g)
what abt the Qc ,though?
U(s) + 3F2(g) ---> UF6(g)
Yes
To balance the equation and write the reaction-quotient expression (Qc) for the given reaction, follow these steps:
Step 1: Write the unbalanced equation:
U(s) + F2(g) <----> UF6(g)
Step 2: Balance the elements other than oxygen and hydrogen:
This equation already has one uranium atom (U) on each side and two fluorine atoms (F) on each side, so they are balanced.
Step 3: Balance oxygen atoms:
Since there is no oxygen (O) in the given equation, no balancing is required.
Step 4: Balance hydrogen atoms:
Since there is no hydrogen (H) in the given equation, no balancing is required.
The balanced equation is:
U(s) + 3F2(g) <----> UF6(g)
Step 5: Write the reaction-quotient expression (Qc):
The reaction-quotient expression, Qc, represents the concentrations of the reactants and products when they are not necessarily at equilibrium. It is written by multiplying the concentrations of the products and dividing by the concentrations of the reactants, each raised to the power of its stoichiometric coefficient.
For the given equation:
Qc = [UF6(g)] / ([U(s)] * [F2(g)]^3)
Note: The concentrations of the substances (U, F2, and UF6) should be given or known to calculate the reaction-quotient expression accurately.
