The IT/ITES industry has contributed around 7.7% of the country's GDP and according to IBEF is a key employment generator with a projection of creating 1.3-1.5 lakh new jobs annually. Which among the following arguments support the above statement in the best possible manner? Arguments: I. The Government has also provided considerable inputs to the industry with its various flagship programmes such as Digital India, Smart Cities, e-Governance coupled with a drive towards a cashless economy. II. The Government has been pro-active in considering demands of the industry and providing timely respite from the teething troubles under GST as well.  III. The IT/ITES industry is a labour intensive industry and a large scale employment generator.

The fresh feed to an ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole per cent inerts. The molar ratio of H2:N2 is 3:1. The product stream consists of pure ammonia. Since conversion in the reactor is only 15%, a recycle stream is used and in order to avoid build-up of inerts, a purge stream is withdrawn. The rate of purge stream is adjusted to keep inert concentration in the recycle stream at 8 mole per cent. For a fresh feed rate of 100 moles/hr. Note that recycle stream contains only nitrogen, hydrogen and inerts. The N2:H2 ratio of 1:3 is maintained in every process stream, and calculate the number of moles, moles of inerts and moles of hydrogen in the recycle stream?
