Activation Energy React to take place caused by its particle, atom or molecule knocking against by energy is certainly (Activation Energy). Activation Energy defined as kinetic energy minimum which must be owned or passed to a particle in order to yield a reaction Hal.: 2 Isi dengan Judul Halaman Terkait

3 Draw the level of activation energy in endoterm reaction

4 Velocity of Reaction Defined
Velocity of Reaction is decrease concentration of A in certain a time gap, with equation V = - Δ [A] / Δ t where, V = velocity in mol/L.s Δ[A] =decrease concentration of A in mol/L Δt = time in second Hal.: 4 Isi dengan Judul Halaman Terkait

6 Guldenberg and Waage Law:
Velocity of reaction at homogeneous system ( one phase) comparing direct with the concentration of reacting rank with the coefficient of each reacting as according to its reaction equation Hal.: 6 Isi dengan Judul Halaman Terkait

7 Persamaan Kecepatan Reaksi
Perhatikan persamaan reaksi dibawah ini : a A → b B Menurut Guldenberg dan Waage, kecepatan reaksi zat A menjadi zat B adalah: V = k.[A] a V = velocity of react k = konstanta kecepatan reaksi [A] dan [B] = konsentrasi zat A dan zat B a dan b = koefisien zat A dan zat B dalam persamaan reaksi Kecepatan react [is] as a whole determined by slowest phase [at] the reaction Hal.: 7 Isi dengan Judul Halaman Terkait

Catalyst. Process the katalisa [is] process take place [it] react with the catalyst existence and there [is] two catalyst type, that is: catalyst: catalyst quickening reaction and inhibitor: catalyst slowing down reaction Autokatalis [is] catalyst formed by itself in a[n reaction Hal.: 10 Isi dengan Judul Halaman Terkait
