Question

A sample of C60O3 decomposes with an activation energy of 50 kg/mol, an Arrehnius pre-factor of 2e10 s-1 and a k value of .04 s-1. How long does it take for a 25 mg sample at 25 degrees C to produce 10 mg.

Your response was is that C60O<suh>3 or what? And I thought Arrhenius equation had to do with k1 and k2 at T1 and T2 and T1 and T2 are tempeataures, not time.

Sorry the last part should be "How long does it take for a 25 mg sample at 25 degrees C to produce 10 mg of C60O. The Arrenhnius stuff was to solve part a to find the k value and I understood that so I just added what I found for k. I thought you are supposed to use the equation, concentration of A equals initial concentration of A times e^(-kt) but I wasn't sure if i could just use the mg as the concentrations or if I had to convert the mg to M or convert between C60O3 and C60O.

Answer 1

You can use the mg directly in the ratge equation. And I made a typo. That first line should have read, "Is that C₆₀O₃
