Recall your study of equilibria and kinetics from general chemistry. You used equations with upper case K and lower case k during the study of equilibria and kinetics respectively. What do the upper and lower case letters refer to?

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
