Phosgene (Cl2CO), a poison gas used in World War I , is formed by the reaction of Cl2 and CO. The proposed mechanism for the reaction is

Cl2⇌2Cl(fast, equilibrium)

Cl+CO⇌ClCO(fast, equilibrium)

ClCO+Cl2→Cl2CO+Cl(slow)

What rate law is consistent with this mechanism?

Which statement correctly describes metallic bonds? a. they form when certain atoms lose electrons and other atoms gain electrons. b. they involve an attraction between anions and cations. they always involvpoth a metal and a nonmetal. d. they can only form between atoms of the same element. e. they form because electrons can move freely between atoms.

Large helium-filled balloons are used to lift scientific equipment to high altitudes. what is the pressure inside such a balloon if it starts out at sea level with a temperature of 10.0ºc and rises to an altitude where its volume is twenty times the original volume and its temperature is – 50.0ºc ?

Na chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.
