A graph is plotted between percentage yields of ammonia vs. pressure at 6 different operating temperatures. According to the graph, at which temperature and pressure yield of ammonia is almost 100%?
(D) 200 ℃ and 1000 atm
Explanation
It is shown through the graph that at 200℃ and 1000 atm pressure yield of ammonia is highest i.e 100%. Alternative explanation: Highest % ammonia yield occurs in the upper-right corner.
