The substitution reaction of 1-bromoethane (C2H5Br) and sodium azide (NaN3) occurs by an SN2 mechanism. What happens to the rate of this reaction if the concentrations of both C2H5Br and NaN3 are doubled

Idon't see the pic?

6because i no yea yea

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
