(a)
Interpretation:
If an ignition source is present and in which solvent vapors will catch fire at room temperature has to be found
Concept introduction:
Flammable: It is a property of a material relating how easily the material ignites (or) sustains a combustion reaction.
Flash point: Flash point of a liquid is the lowest temperature at which it gives off enough vapour to from an ignitable mixture with air.
Ignition: It is a flammable mixture may be caused by flammable mixture coming in content with a source of ignition with sufficient energy (or) the gas reacting a temperature high enough to cause the gas to autoignite.
(b)
Interpretation:
The auto ignition temperatures of the solvents found in Dr. Thompson’s laboratory and any of these solvents combust without presence of an outside source of ignition, the reason behind this has to be explained.
Concept introduction:
Flammable: It is a property of a material relating how easily the material ignites (or) sustains a combustion reaction.
Ignition: It is a flammable mixture may be caused by flammable mixture coming in content with a source of ignition with sufficient energy (or) the gas reacting a temperature high enough to cause the gas to autoignite.
Autoignition: The auto ignition temperature (AIT) corresponds to the minimum temperature at which the vapour spontaneously ignites, even in the absence of an ignition source.

Solar chemical refers to processes that harness and store solar energy by adsorbing light in a reversible chemical reaction. For example, the photodimerization of anthracene absorbs and stores solar energy that can be released when the reverse reaction takes place. hv Anthracene dimerization. Another reaction of interest is the Norbornadiene- Quadricyclane (NQ) couple, where solar energy is adsorbed and stored in one direction and released in the other. hv The Norbornadiene- Quadricyclane (NQ) couple is of potential interest for sunlight energy storage. A. Suggest a rate law for the reversible photodimerization of anthracene. B. Suggest a rate law for the reversible storage of energy by the NQ couple.arrow_forward
