GCSE Chemistry Question Analysis Topic: Chemistry - Short Questions
Exam Questions:
1) What is the effect of temperature on chemisorption?
2) What are the products of hydrolysis of sucrose?
Answers:
For GCSE Chemistry, you should know:
1) With an increase in temperature, chemisorption initially rises before falling. The first rise is caused by the heat being delivered, which serves as activation energy. The exothermic nature of the adsorption equilibrium is what causes the subsequent decline.
2) When sucrose is hydrolyzed, dextrorotatory glucose and laevorotatory fructose are produced in an equimolar combination. Due to the fact that the sign of rotation changes from (+) to (-) during sucrose hydrolysis, the result is known as invert sugar.
Work hard for your GCSE Chemistry examination!
End of analysis. Great!
