[radicality]

Hello everyone. So im doing my lab and this is how far I've gotten. It's about the decomposition of Hydrogen peroxide with a catalyst. I measured the amount of oxygen released over time. So I got this data but how do I get it now to be R=K[H202]^x ? How do I find x and k? Thanks a lot.

Solution   [H2O2] mol/dm3   Rate ((mol/dm3)/s)
a)                     0.5                    0.00735
b)                     1.0                    0.01301
c)                     1.5                    0.01358

Once you solve for x, you can plug it into the expression with any rate and concentration you have and solve for K.
