Answer 11:
A limiting reactant is a species which is present in limiting amount for a complete reaction or complete reactants to product conversion to occur. Here, 3 moles of hydrogen and one mole of nitrigen needs to be there i.e. 3:1 ratio of hydrogen to nitrogen for 2 moles of ammonia preparation.
Given: 4 moles of hydrogen and 2 moles of nitrogen i.e. 2:1 ratio of hydrogen to nitrogen. The above ratio is lesser than 3:1 ratio for complete reaction. Therefore, hydrogen is a limiting reactant. i.e. option (d)
Note: If two additional moles will be there, then total 6 moles of hydrogen with 2 moles of nitrogen will result in 3:1 ratio, and so complete reactant to product formation will occur.
Answer 12:
A reduction is a process where electrons gets absobed by the chemical species, resulting in reduction of positive charge on chemical species. Here,
