1. 28. Which does NOT change with time for a first-order reaction? (A) the amount of reactant that disappears in each half- life (B) the concentration of the reactant (C) the length of each half-life (D) the rate of the reaction
Pada reaksi order pertama yang tidak mengalami perubahan adalah :
C. The length of each half-life
Pembahasan
Reaksi orde pertama adalah reaksi dalam orde menetap, laju reaksi berbanding lurus dengan konsentrasi salah satu reaktan. Reaksi orde pertama sering memiliki bentuk umum A → produk. Tingkat diferensial untuk reaksi orde pertama adalah sebagai berikut:
laju=−Δ[A]/Δt=k[A]
Jika konsentrasi A digandakan, laju reaksi menjadi dua kali lipat, jika konsentrasi A dinaikkan dengan faktor 10, laju reaksi meningkat dengan faktor 10, dan seterusnya. Karena satuan laju reaksi selalu mol per liter per detik, satuan konstanta laju orde pertama adalah detik timbal balik (s−1). Hukum laju terintegrasi untuk reaksi orde pertama dapat ditulis dalam dua cara yang berbeda: satu menggunakan eksponen dan satu menggunakan logaritma. Ingat bahwa hukum laju terintegrasi memberikan hubungan antara konsentrasi reaktan dan waktu.

6. Why is concentration vs reaction rate linear for first order reaction ?
The reason why on order 1 reaction the concentration and reaction rate is linear for first order reaction, That's because experiments have shown that the rate of a reaction is directly proportional to the concentration.
Pembahasan
Reaksi primer adalah reaksi yang laju reaksinya sebanding dengan konsentrasi reaktannya. Dengan kata lain, menggandakan konsentrasi menggandakan laju reaksi. Reaksi primer dapat memiliki satu atau dua reaktan, seperti dalam kasus reaksi dekomposisi. Reaksi primer dapat didefinisikan sebagai reaksi kimia di mana laju reaksi bergantung secara linier pada konsentrasi hanya satu reaktan. Dengan kata lain, reaksi primer adalah reaksi kimia yang lajunya berubah berdasarkan perubahan konsentrasi hanya satu reaktan. Jadi orde reaksinya adalah 1.

Jawaban:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
