The decomposition reaction of carbon disulfide, CS2, to carbon monosulfide, CS, and sulfur is first order
with k = 4.89x10-7 S-1 at 800. C.
CS2 → CS + S
What is the half-life of this reaction at 800.'C?

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

i think that the answer is c

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

the objects have the same charge is correct.
