Chemical kinetics is the study of the .................................... of chemical reactions

• rate and speed

• rate and mechanism

• stoichiometry

• reaction mechanism

Rate of the reaction =-(change in the concentration of reactants/?)

• time

• speed

• change in the concentration of products

• power

Let us consider a simple general reaction   A   GIVES 2B

• (+ⅆ[A])/ⅆt

• (+ⅆ[B])/ⅆt

• (-ⅆ[B])/ⅆt

• (-ⅆ[A])/ⅆt

Cyclopropane gives .....................

• propane

• propene

• butane

• butene

The rate of the reaction, at a particular instant during the reaction is called the ...........................

• average rate

• instantaneous rate

• normal rate

The rate law for the above reaction is generally expressed as

.......................

• Rate =k[A]^m [B]^n

• Rate =k[b]^m [B]^n

• Rate =k[c]^m [B]^n

• Rate =k[l]^m [B]^n

.................=proportionality constant?

• p

• k

• l

• m

Rate of a reaction represents the ...................... at which the reactants are converted into products at any instant

• concentration

• speed

• time

• velocity

.............................. depends on the initial concentration of reactants.

• rate

• time

Rate constant of a reaction ........................... on the initial concentration of reactants.

• depend

• does not depend
