How is the entropy change of the surroundings (ΔSsurr) calculated?
Understand the Problem
The question is asking to identify the correct formula for calculating the entropy change of the surroundings (ΔSsurr) from the provided multiple-choice options.
Answer
ΔSsurr = (−ΔHsys)/T
The entropy change of the surroundings (ΔSsurr) is calculated using the formula: ΔSsurr = (−ΔHsys)/T.
Answer for screen readers
The entropy change of the surroundings (ΔSsurr) is calculated using the formula: ΔSsurr = (−ΔHsys)/T.
More Information
This formula calculates the entropy change of the surroundings based on the change in enthalpy of the system (ΔHsys) and the temperature (T). It's typically used in thermodynamics to assess energy dispersion in chemical processes.
Tips
A common mistake is forgetting to convert the change in enthalpy (ΔHsys) from kJ to J before using it in the formula.
