OP An increase in concentration (or pressure) increases rate of reaction
because...
B: the collision frequency is increased
A the arvaton energy is increased
D. All of these
there are more unsuccessful
collisions

Why doesn't heat added to water make the tempature rise above 100c

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?

[ou.03jthe pictures below show the wavelengths and intensities of electromagnetic radiations emitted by three stars, star 1, star 2, and star 3. intensity intensity- intensity- 1000 3500 6000 8500 11000 wavelength (a) star 1 1000 3500 6000 8500 11000 1000 3500 6000 8500 11000 wavelength (a) wavelength (a) star 2 star 3 which of these statements is correct about the color of the three stars? star 2 is white in color o star 2 is yellow in color star 1 and star 3 are yellow in color star 1 and star 3 are white in color
