4 marks for each exampleyea i know that...bu-ut for 8 marks i donno how to elaborate...ESP! 'How the catalyst u've chosen helps to decrease the Ea! Please
Jazak allah Khair ! May Allah bless u!
1 mark for example
1 mark for telling which type of catalysis it is
1 mark for reaction equation
1 mark for what Cat is doing (except meeeow )
u got the first three i hope so
for the last mark in both example:
a(Iron here is used as increasing the surface area where reagants are adsobed on its surface to increast the number of efficient collisions ...)
b(If Fe2+ is used it will reduce to Fe3+ bu oxidizing peroxydisulfide(s2o8)^2-
the Fe3+ ion now convert I- ions to I2 guys and Fe2+)
for b: the reaction in water is over all slow so homogenous catalysis(Fe2+) introduced to fasten the reaction by stated above(at the end u get Fe2+ ions back)
hope this helps please pray for me
