Final answer:
The standard potential for a cell generally decreases with an increase in temperature. The standard potential of the cell in the previous question will decrease if the temperature is increased. The exact value of the standard potential at 79 °C cannot be calculated without specific temperature-dependent data or equation.
Step-by-step explanation:
The standard potential for a cell generally decreases with an increase in temperature. The standard electrode potentials are typically measured at a fixed temperature, usually 25°C. When the temperature is increased, the equilibrium constants for the redox reactions involved in the cell may be affected, leading to a change in the standard potential Therefore, based on the relationship between temperature and standard potential, the standard potential of the cell in the previous question will decrease if the temperature is increased.
To determine the standard potential of this cell at 79 °C, specific temperature-dependent data or equation relating temperature and standard potential is required. Without that information, we cannot calculate the exact value of the standard potential at 79 °C.
