Given the following proposed mechanism, predict the rate law for the rate-determining step.

2 NO2 + Cl2 → 2 NO2Cl (overall reaction)

MechanismNO2 + Cl2 → NO2Cl + Cl (slow)NO2 + Cl → NO2Cl (fast)A) Rate = k[NO2][Cl]B) Rate = k[NO2Cl][Cl]C) Rate = k[NO2]2[Cl2]D) Rate = k[NO2][Cl2]E) Rate = k[NO2Cl]2

D) Rate = K [NO2][Cl2]

Explanation:

2 NO2 + Cl2 → 2 NO2Cl (overall reaction)

NO2 + Cl2 → NO2Cl + Cl (slow)

NO2 + Cl → NO2Cl (fast)

The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.

Rate of reaction is typically given as;

Rate = K [Reactants]

In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.

Rate = K [NO2][Cl2]

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
