The following mechanism has been proposed for the gas-phase reaction of chloroform (chcl3) and chlorine:

step 1: cl2(g)⇌2cl(g)(fast)
step 2: cl(g)+chcl3(g)→hcl(g)+ccl3(g)(slow)
step 3: cl(g)+ccl3(g)→ccl4(fast)

what is the overall rate constant?

Achemist has dissolved a certain substance in water. the chemist knows that more of the substance could be dissolved into the water before it stops dissolving. therefore
