Speed constant data against temperature were obtained for the reaction. Calculate the coefficients at the Arrhenius threshold. Temperature (°C) Speed constant (mol L-1 s-1)
200 2.91 x 10-6
300 8.38 x 10-4
400 7.65 x 10-2
500 6.73 x 10-1

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.

a electronegativity decreases beacuse the size of nucleus is bigger.
