A student conducted two laboratory experiments to investigate the rate of reaction of sulphuric acid with calcium carbonate to collect 50 cm3 carbon dioxide gas.
Table 4 shows the results of the experiment.
Which of the following statements is true?
Seorang pelajar menjalankan dua eksperimen makmal untuk menyiasat kadar tindak balas bagi asid sulfurik cair dengan kalsium karbonat bagi mengumpulkan 50 cm3 gas karbon dioksida.
Jadual 4 menunjukkan keputusan eksperimen tersebut.
Antara pernyataan berikut, yang manakah benar?
The rate of reaction in Experiment II is higher than in Experiment I
Kadar tindak balas Eksperimen II lebih tinggi berbanding Eksperimen I
The bigger the size of calcium carbonate, the bigger the exposed surface area
Semakin besar saiz kalsium karbonat, semakin bertambah luas permukaan terdedah
The smaller the surface area of the reactant exposed, the higher the rate of reaction
Semakin berkurang luas permukaan bahan tindak balas terdedah, semakin bertambah kadar tindak balas
