Question

Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the following reaction equation.

Answer 1

Canceling out the constants and taking the natural log of both sides gives us this: 


Ea1/T1=Ea2/T2 

Ea1=75kJ 
T1=298K 

Ea2=49kJ 
T2=? 

So now, 

T2= Ea*T1/Ea = 75*298/49 

Your answer should be 456.12 = 456K!
