Answer 1

The question asks about the work done by steam during isothermal expansion using the Van der Waals equation, but essential information such as the final volume and the value of the Van der Waals constant 'a' is missing, making it impossible to provide a numerical answer.

Step-by-step explanation:

The question involves calculating the work done by a gas during an isothermal expansion using the Van der Waals equation. In the provided scenario, Marissa uses 5 moles of steam at a temperature of 226.85 K that is initially at a volume of 7 m³. The steam then expands isothermally to an unspecified final volume, and the Van der Waals constants provided are a (which seems to be missing in the question) and b = 0.7 m³/mol.

To find the work done by the gas during this isothermal expansion, we would need to integrate the Van der Waals equation for pressure with respect to volume from the initial volume to the final volume. However, the final volume is not specified in the question, and the value for a is missing, which are both necessary to perform the calculation. Because of these missing elements, it is not possible to provide a numerical answer to the question.
