Answer : B ) Low Temp, High Pressure
Explanation :
Haber method :
N2 (g) + 3 H2 (g) -----------> 2 NH3 (g) , delta H = - 22 kcal
here the reaction is exothermic reaction .
so at low temperature , the reaction shifts to product side. so more NH3 is produced.
at high pressure , reaction shifts to fewer number of moles of gas. so here also more NH3 will produced.

Problem No-2 A chemical plant needs a micro-processor-driven alarm system to warn of critical conditions in one of its chemical tanks. The tank has four HIGH/LOW (1/0) switches that monitor temperature (T), pressure (P), fluid level (L), and weight (W). Design a system that will notify the micro-processor to activate an alarm when any of the following conditions arise: High fluid level with high temperature and high pressure Low fluid level with high temperature and high weight Low fluid level...
