Final answer:

Estimating the absolute enthalpy of carbon disulfide at 94K requires specific data which is not provided, but values would typically be lower than standard state enthalpies.

Step-by-step explanation:

To estimate the absolute enthalpy of carbon disulfide at 94K, it is important to consider that absolute enthalpy is a challenging concept, as absolute zero enthalpy is not experimentally accessible. However, the question seems to be asking for an estimate of the enthalpy change at a low temperature, such as 94K. Since none of the information provided allows for a direct calculation of the enthalpy of carbon disulfide at this temperature, and typical standard enthalpy values are given at 298K, we cannot give an accurate estimation without additional data specific to carbon disulfide. In general, the absolute enthalpies at low temperatures tend to be lower relative to standard state enthalpies due to less kinetic energy present in the molecules. Therefore, choices such as 150 kJ/mol and 200 kJ/mol could be considered closer estimates compared to higher values, but without the specific heat capacity of carbon disulfide or data on its behavior at low temperatures, an exact answer cannot be determined.
