SOLN 3
(a) rate : whenever any quantity like concentration, pressure etc changes with time , then we will define its rate . rate is nothing but change of something with time
(b) rate law : it gives mathematical relationship how the quantity changes with concentration, pressure etc in due course of time. it is given by law of mass action which state that rate is directly proportional to active mass of reactant raised to their power of its stoichiometric coefficient
eg A ---- > B
rate law is
(c) rate constant : when we remove proportinality sign we get constant which is called rate constant. it is basically a coefficient of proportionality which mathematically relates the rate any particular reaction to the concentration of reactant
According to HOMEWORKLIB POLICY only 1 question per post is allowed. please post the rest question seperately.
Hope you understand!!!
