(b) Do compounds of hydrogen exhibit a relatively large or small kinetic isotope effect? Explain.
joja [24]

Compounds of hydrogen exhibit a relatively large kinetic isotope effect.

The phenomenon known as the kinetic isotope effect (KIE) is brought on by the variable reaction speeds that are displayed by isotopically substituted compounds. When it comes to studying reaction kinetics, mechanisms, and solvent effects, isotope effects like KIEs are invaluable tools in both physical and biological sciences.

The phenomenon known as the kinetic isotope effect (KIE) is brought on by the variable reaction speeds that are displayed by isotopically substituted compounds. When it comes to studying reaction kinetics, mechanisms, and solvent effects, isotope effects like KIEs are invaluable tools in both physical and biological sciences. The replacement of hydrogen with deuterium is a highly frequent isotope substitution. The ratio kH/kD, which describes this as a "deuterium effect," is used to measure it. Due to the proportion, significant effects are observed.

When water is solid, do molecules move?
BabaBlast [244]

Answer:

Ice is water in its solid form. Ice keeps its shape, even if it's removed from the container. The molecules in ice are locked into place and cannot move or slide past one another, but they do vibrate a little bit.

Explanation:

As the temperature drops or decreases, the water molecules gradually slow down. Eventually they stop moving and simply vibrate back and forth. At this point ice is formed, the solid phase of water. If the temperature is allowed to increase, the molecules will once again begin to vibrate faster and faster.
