Answer:
The equilibrium will shift to the left to favor the reactants.
Explanation:
Remember that the reaction quotient (Qc) is derived from initial concentrations of reactants and products. Since Qc is greater than Kc, this means that initial concentrations are heavily impacted by a high product concentration ([HI]). Therefore, the reverse reaction will occur and actually create more reactants again ([H2] and [I2]). Thus, the answer is that the equilibrium will shift to the left side to favor the reactants.
You would calculate them by dividing them and then multiplying to get the final answer
Answer:
The pOH of the solution is 9.92
Explanation:
pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance. PH is defined as the negative logarithm (base 10) of the hydronium ion concentration [H₃O⁺]:
pH= - log [H₃O⁺]
So, if [H₃O⁺]=8.26*10⁻⁵, the pH is: pH=- log (8.26*10⁻⁵) ⇒ pH= 4.08
The pOH measures the concentration of OH− ions. The following relationship can be established between pH and pOH:
pH + pOH= 14
In this case, being pH=4.08 and replacing in the relationship between pH and pOH:
4.08 + pOH=14
Solving:
pOH= 14 - 4.08
pOH= 9.92
The pOH of the solution is 9.92
