Abstract

4. The number of moles of hydrogen molecules required to produce 20 moles of ammonia through Haber’s process is : (1) 10 (2) 20 (3) 30 (4) 40 (3) [NCERT XI-I-17] N2 + 3H2  2NH3 for 20 moles of NH3, 30 moles of H2 are required. 5. For an ideal solution, the correct option is : (1) mix S=0 at constant T and P (2) mix V 0 at constant T and P (3) mix H=0 at constant T and P (4) mix G=0 at constabnt T and P (3) [NCERT XI-I-45] For ideal solution S > 0, G < 0, H = 0 V = 0
