Which of the following best defines work? Choose one: A. The study of the relationship between chemical reactions and changes in energy B. The energy transferred between objects because of a difference in their temperature C. The energy required to move an object through a given distance D. The chemical equation of a reaction that includes energy as a reactant or a product

correct option: C

Explanation:

work is the energy required to move an object even in case of piston cylinder case work is calculated which is done by motion of pitson.

Work is defined as by the system on its surroundings as negative

work is not state funcion it is a path funcion and different for different path.

if there is no movement in the direction of the force means no work done by force in that dirrection.

hence opion c is correct

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
