Answer:
The correct answer is option a.
Explanation:
Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in ().
J = diffusion flux
A = Unit area A through which atoms moves.
M = mass of atoms passes in t interval of time.

Explanation:
In organic chemistry, a product may be kinetically or thermodynamically favoured. A kinetically favours product forms faster, it may not necessarily be the more stable product. The thermodynamically favoured product forms at a slower rate but is more stable. Often times, the kinetically favoured product rearranges itself to form the thermodynamically favoured product at equilibrium. The endo product of the Diels Alder reaction mentioned in the question is first formed (kinetically favoured) but rearranges to form the exo product (thermodynamically favoured) at equilibrium. This is clear shown in the reaction mechanism attached below.
