Pernyataan yang benar tentang reaksi endoterm adalah

Ringkasan atau inti cerita pada cerpen terletak pada? 

Pernyataan yang benar tentang reaksi endoterm adalah ….

A. Entalpi awal lebih besar daripada entalpi akhir ; ∆H > 0

B. Entalpi awal lebih kecil daripada entalpi akhir ; ∆H > 0

C. Entalpi awal lebih besar daripada entalpi akhir ; ∆H < 0

D. Entalpi awal lebih kecil daripada entalpi akhir ; ∆H < 0

E. Entalpi awal sama dengan entalpi akhir ; ∆H = 0

 

Jawaban: B. Entalpi awal lebih kecil daripada entalpi akhir ; ∆H > 0

 

Pembahasan: 

Reaksi endoterm adalah reaksi menyerap kalor. Terjadi perpindahan kalor dari lingkungan ke sistem. Akibatnya entalpi awal lebih kecil dari entalpi akhir, dan nilai ∆H > 0.

Pertanyaan Berikutnya: Pernyataan yang tidak sesuai dengan teori sel adalah
