Question

The Kₛₚ for NiS at 298 K is 1.2e-21. What is the Kₛₚ for NiS at 344 K?

a) 1.2e-21
b) 1.7e-21
c) 2.5e-22
d) 8.9e-23

Answer 1

The K_sp for NiS at 344 K cannot be accurately determined from the given options without additional temperature-dependent data or the Van't Hoff equation.

Step-by-step explanation:

The student has asked what the solubility product constant (Ksp) for NiS is at 344 K, given that the Ksp at 298 K is 1.2e-21. It's important to note that in general, the solubility product constant, a type of equilibrium constant, is temperature-dependent. However, without additional data, such as the enthalpy of the dissolution process, a standard equation like the Van't Hoff equation, or experimental results at the new temperature, we cannot accurately calculate the Ksp at a different temperature. Consequently, the Ksp for NiS at 344 K cannot be determined with the given options a) 1.2e-21, b) 1.7e-21, c) 2.5e-22, or d) 8.9e-23 without additional data. Therefore, any answer selected from the given options would not be accurate.
