RATE OF REACTION Level of change of concentration of reactant or product in one set of time Rate of reaction = concentration change time change Example: Rate of reaction = Hal.: 5 Isi dengan Judul Halaman Terkait

6 Factors influencing rate of reaction;
Concentration of reactant Ever greater concentration of reactant hence rate of reaction would be quicker taken place Character reactant Reaction of between ionic compounds generally takes place quickly, while reacting between covalent compounds to take place is slow Hal.: 6 Isi dengan Judul Halaman Terkait

Temperature If temperature is boosted up [by] hence reaction will take place is quicker Catalyst Catalyst is matter added into a having a purpose reaction enlarges reaction speed, catalyst will react but end reaction will be formed again in the form and number of the same like before reactions Hal.: 7 Isi dengan Judul Halaman Terkait

FUNCTION OF CATALYST Function of catalyst is enlarge speed of its the reaction (quickens reaction) by way of minimizing activation energy a reaction and formed [by] it new reaction phases. With lowering of activation energy hence at the same temperature reacted can take place quicker. Hal.: 8 Isi dengan Judul Halaman Terkait

REACTION ORDER Order a reaction is number of all exponents ( from concentration of in rate equation). Order reaction of also express level of influence concentration of ( reactant) to rate of reaction Reacted first order if Rate=k[A] Reacted second order if Rate=k[A][B] Reaction of third order, Rate=k [ A][B]2 Hal.: 9 Isi dengan Judul Halaman Terkait

10 DETERMINES REACTION ORDER
Reaction 4HBr + O2  2H2O + 2Br2 takes place in step; Step 1; HBr + O2  HOOBr (slow) Step 2; HBr + HOOBr  2HOBr (fast) Step 3; 2HBr + 2HBrO  2H2O + 2Br2 (fast) Hence order reaction of determined by reaction ( 1). Rate equation of Reaction: V=[HBr][O2] Order reaction of total ( sees reaction coefficient) = = 2. Hal.: 10 Isi dengan Judul Halaman Terkait

EXAMPLE OF PROBLEM Reaction; P + Q + R  X + Y, obtained attempt data as follows : Order reaction of to P, searched by seeing concentration [Q] and [ R] which permanent. From data ( 1) and ( 3), known concentration [ Q] and [ R] permanent, [ P] boosted up twice. So reaction of taking place 2 quicker times. Number [P] [Q] [R] Times 1 0,1 0,2 6 minute 2 0,3 3 3 minute 4 5 2 minute Hal.: 11 Isi dengan Judul Halaman Terkait

PROBLEM SOLVING Order reaction of to Q, searched by seeing concentration [ P] and [ R] which is permanent namely as follows. Data ( 4) and ( 5)  1,5 quicker times Data ( 1) and ( 4)  2 quicker times Data ( 1) and ( 5)  3 quicker times Remembers : order reaction of determined by slowest reaction phase Hal.: 12 Isi dengan Judul Halaman Terkait

Order reaction of to R, hence view data ( 1) and ( 2) where concentration [ P] and [ Q] permanent. Concentration Of r is boosted up [by] 1,5 times, simply reaction of taking place is same quickly. Hence rate equation of its(the reaction is as follows: V = k [ P] [ Q] Hal.: 13 Isi dengan Judul Halaman Terkait
