3) In haber process, 20% is produced at sets of optimum conditions like 450^circ C and 200 atm pressure. Which of the conditions below are not optimum a) 1.52times 10^5Pa and 723K b) 200atm and 450^circ C c) 760mmHg and 450^circ C d) 2.0times 10^2atm and 723K

To determine which conditions are not optimum for the Haber process, we need to compare the given conditions with the optimum conditions of 450°C and 200 atm pressure.<br /><br />Let's analyze each option:<br /><br />a) $1.52\times 10^{5}Pa$ and 723K<br /> - This condition has a pressure of $1.52\times 10^{5}Pa$, which is equivalent to 152 atm.<br /> - The temperature is 723K, which is equivalent to 450°C.<br /> - This condition has a pressure that is significantly higher than the optimum pressure of 200 atm.<br /><br />b) 200atm and $450^{\circ }C$<br /> - This condition has a pressure of 200 atm, which matches the optimum pressure.<br /> - The temperature is 450°C, which also matches the optimum temperature.<br /> - This condition is the same as the optimum conditions.<br /><br />c) 760mmHg and $450^{\circ }C$<br /> - This condition has a pressure of 760 mmHg, which is equivalent to 1 atm.<br /> - The temperature is 450°C, which matches the optimum temperature.<br /> - This condition has a pressure that is significantly lower than the optimum pressure.<br /><br />d) $2.0\times 10^{2}atm$ and 723K<br /> - This condition has a pressure of $2.0\times 10^{2}atm$, which is equivalent to 200 atm.<br /> - The temperature is 723K, which is equivalent to 450°C.<br /> - This condition has both the optimum pressure and temperature.<br /><br />Based on the analysis, the conditions that are not optimum for the Haber process are:<br /><br />a) $1.52\times 10^{5}Pa$ and 723K<br />c) 760mmHg and $450^{\circ }C$<br /><br />Therefore, the correct answer is:<br />a) $1.52\times 10^{5}Pa$ and 723K<br />c) 760mmHg and $450^{\circ }C$
