1,Given That Ea For The Hydrolysis Of Sucrose Is 108x10^3 KJ/mol,compare The Rate Constant Of Ths Reaction at 37degree C,(T1) with the rate constant of the same reaction at 27degree C,(T2).

2,calculate the rate constant for the above reaction at 47degree C&compare it to the rate constant at 37degree C,
3,plot agraph of log k versus 1/T to calculate the activation energy.

Use the Arrhenius equation for 1 an 2. Can't draw on this site for 3.
Arrhenius equation is
ln k1/k2 = -Ea(1/T1 - 1/T2)/R.
The problem doesn't give either k1 or k2 and since you want to compare, I would solve for the ratio of k1/k2. Post your work if you get stuck.
1 and 2 are worked the same way. You may be able to find an "arrhenius calculator" on-line if you looked for it.
