Question

Based on the following reaction for nitrification, would you expect this to increase or decrease alkalinity? 1. NH? + 1.502 NO? + 2H+ + H20 a. Increase b. Decrease c. Not change d. Not enough information provided Based on the following reaction for denitrification, would you expect this to increase or decrease alkalinity? 2. 2NO? + 10e-+ 12H+ ? N2 + 6H20 a. Increase b. Decrease c. Not change d. Not enough information provided 3. A reaction has the following kinetic rate expression: dc/dt -k. This reaction is: a. First Order. b. Zero Order. c. Second Order d. In equilibrium.

Explanation / Answer

Ans 1 : b) decrease

The nitrification reaction in the soil yields protons in the form of products. These protons increase the acidity of the soil , or decrease the alkalinity . The decrease in pH causes the nitrification reaction to cease. The reaction stops if the soil pH drops below 4.5 level.
