6.
During an electrochemistry lab session, a student uses the Nernst Equation to calculate the cell potential ($ E_{\text{cell}} $) of a galvanic system at a non-standard temperature. Which parameter option accurately defines the scaling behavior of the cell potential relative to changes in the reaction quotient ($ Q $)?

As the concentration of product ions increases relative to reactant ions (increasing $ Q $), the value of $ E_{\text{cell}} $ decreases.
The value of $ E_{\text{cell}} $ increases linearly with an increase in the value of $ Q $.
The value of $ E_{\text{cell}} $ remains completely independent of any concentration shifts in $ Q $.
An increase in $ Q $ causes an exponential jump in the net electrical voltage produced.
