(a)
Interpretation: For the given initial temperature of the catalyst, the temperature-time trajectory has to be determined.
Concept Introduction:
Temperature-time trajectory: In the word temperature-time trajectory, the word trajectory literally means the path. So temperature-time trajectory means the curve that is described by the temperature and time co-ordinates.
(b)
Interpretation: The catalyst lifetime has to be found.
Concept Introduction:
Catalyst lifetime:
A catalyst is a species that can enhances the rate and the selectivity of a chemical reaction by involving itself. It will be regenerated at the end of the reaction without any chemical change. The time period up to which a catalyst can sustain its catalytic activity is known as the Catalyst lifetime.
