Which of the following crops helps in nitrogen fixation?

Which of the following crops helps in nitrogen fixation? Correct Answer Beans

Legume crops such as beans, peanuts and soy can fix nitrogen from the air, and flourish on nitrogen - deficient soils. To do so, they need help from Rhizobium bacteria. These special bacteria stimulate the growth of nodules on the roots of leguminous plants.

In order to prepare Lithium nitride, air is passed gently over a reactor. Suppose that Nitrogen diffuse to a length 5cm before getting reacted with Lithium. Nitrogen reacts with lithium quickly so that partial pressure of Nitrogen at that point is 0. Reactor is a cylinder of length 10cm and diameter 2cm. Assume air to be a mixture of Nitrogen and Oxygen only. The temperature is 298K and total pressure 1atm. Diffusivity of N2 in O2 is 2*10-5m2/s. Calculate the Molar flux (mol/m2.s) of N2 at a distance of 2.5cm from the top with respect to an observer moving with twice the mass average velocity a direction towards the liquid surface. (R=8.205*10-5m3atmK-1mol-1). Assume z=0 at the top of the reactor.
