Application Aplikasi

Meaning / Maksud

RATE OF REACTION

Factors affect rate of reaction Faktor mempengaruhi kadar tindak balas

KADAR TINDAK BALAS

Experiments on the effect of Eksperimen tentang kesan

Can be explained using Boleh diterangkan menggunakan

Temperature Suhu

Concentration Kepekatan

Catalyst Mangkin

The larger the size of solid reactant, the less total surface area expose to collision Semakin besar saiz pepejal bahan tindak balas, semakin berkurangan jumlah luas permukaan yang terdedah kepada perlanggaran

The higher the temperature, the higher the kinetic energy of particles Semakin tinggi suhu, semakin tinggi tenaga kinetik zarah

The higher the concentration of solution, the higher the number of particles per unit volume Semakin tinggi kepekatan larutan, semakin tinggi bilangan zarah per unit isi padu

The presence of catalyst lower the activation energy of the reaction Kehadiran mangkin merendahkan tenaga pengaktifan tindak balas
