Question 1

True or false: Arrhenius developed the pH scale for measuring acidity.

Accepted Answer

False. The pH scale was invented by Søren Sørensen in 1909, not Arrhenius. Arrhenius focused on dissociation, not pH.

Question 2

True or false: Arrhenius coined the term 'activation energy' in chemical reactions.

Accepted Answer

True. He introduced the concept of activation energy and the Arrhenius equation, linking reaction rates to temperature and energy barriers.

Question 3

True or false: Arrhenius was a professor at the University of Cambridge for most of his career.

Accepted Answer

False. He spent most of his career at Stockholm University (then Stockholms Högskola) and the Nobel Institute, not Cambridge.

Question 4

True or false: Svante Arrhenius was awarded the Nobel Prize in Chemistry in 1903.

Accepted Answer

True. He received the Nobel Prize for his electrolytic dissociation theory, which he had proposed in his 1884 doctoral thesis.

Question 5

True or false: Arrhenius won the Nobel Prize in Chemistry for his theory of acids and bases.

Accepted Answer

False. He won the 1903 Nobel Prize in Chemistry for his electrolytic dissociation theory, not specifically for defining acids and bases.

Question 6

True or false: Arrhenius believed life could survive on Venus due to its thick atmosphere.

Accepted Answer

False. He considered Venus too hot and dry to support life as we know it, based on his greenhouse theory.

Question 7

True or false: Svante Arrhenius proposed that microscopic life could travel through space via radiation pressure from stars.

Accepted Answer

True. He coined the term 'panspermia' and suggested that spores or microorganisms could be propelled by light pressure, potentially spreading life between planets.

Question 8

True or false: Arrhenius was the first scientist to calculate the greenhouse effect from CO2.

Accepted Answer

True. In 1896, Arrhenius published a paper calculating that doubling CO2 could raise Earth’s temperature by 5–6°C, long before modern climate science.
