Answer:
In Homogenous mixtures, the whole mixture is in the same phase whereas in Heterogeneous mixture, substances can be of two phases and layers may separate. ... Homogeneous mixture could be exemplified as a sugar solution or salt solution whereas Mixture of salt and sand could be used as an example of Heterogeneous mixture.
Answer:
(C) substance B is not involved in the rate-determining step of the mechanism but is involved in subsequent steps.
Explanation:
A. Is incorrect because if the order of the reaction with respect B was one then the rate would increase by the same multiple that B is increased by.
B. If B is reactant then it must be involved in the mechanism of the reaction and in the formation of the product
D. If B was a catalyst then increasing it's amount would affect the rate
E. That is just factually untrue. Effect of reactants on rates can only be found experimentally, not stoichiometrically.
Answer:
C.
Explanation:
Exothermic means the energy of products is lower than energy of reactants. Transition state will always be the highest energy among the two.
