Concept explainers
Interpretation:
The Lewis structure of vinyl chloride, repeating units of vinyl chloride, and the enthalpy change are to be calculated.
Concept Introduction:
The standard enthalpy for a reaction is the amount of enthalpy change that occurs to occur understandard conditions(room temperature and pressure)
The enthalpy of reaction can be calculated as:
Here, BE represents the average value of bond enthalpy.
