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?

Which describes fat? a: a carbohydrate that produces energy b: a nucleic acid that directs cell function c: a lipid that stores energy d: a protein that speeds up a chemical reaction

How is the solubility of a carbon dioxide gas in water increase?

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
