CHEMISTRY DOUBT

PAPER 62 JUNE 2010 QUESTION 4 PART E) ii)

ANY HELP WOULD BE APPRECIATED

Make sure you read the question very carefully for instructions.
In the beginning of Q4, it says two DIFFERENT acids were used, so Expt1 is faster than Expt2 because Acid D is maybe weaker or less concentrated than Acid C.
Hope you understand the Ques. now =)

thanks for your help, but you probably have checked paper 61 where acid C is more concentrated. While in papaer 62, acid D is more concentrated, so there would be more frequent collisions producing more heat and hence greater temperature change,
