Question

Balance the reaction NO3 − + H2 = NH4 + + H2O + OH− ii. The initial pH of the reaction was 3.0 adjusted by 1 mM HCl because the reaction was active in acidic conditions (pH < 4). If the initial concentration of nitrate was 1 mM, what will happen after the reaction started? iii. Still at pH 3 with 1 mM HCl, if the initial concentration of nitrate was 1 μM, what will happen after the reaction started?

Answer 1

NO3- + 2H2 = NH4+ + H2O + 2OH-

Step-by-step explanation:

If the initial concentration of nitrate was 1 mM, the reaction will be faster due to higher concentration of the nitrate.

if the initial concentration of nitrate was 1 μM, the reaction rate will be very slow due to the lower concentration of the nitrate
