The rate of bacterial hydrolysis in fish muscle (the main mechanism of fish muscle decomposition--it makes the fish go stinky) is twice as great at 2.2 C than it is at -1.1 C. Estimate an activation energy for this reaction. Is there any relation of the problem of storing fish for food?

The enzyme urease enhances the rate of urea hydrolysis at pH 8.0 and $20^{\circ} \mathrm{C}$ by a factor of $10^{14}$. If a given quantity of urease can completely hydrolyze a given quantity of urea in 5.0 min at $20^{\circ} \mathrm{C}$ and $\mathrm{pH}$ $8.0,$ how long would it take for this amount of urea to be hydrolyzed under the same conditions in the absence of urease? Assume that both reactions take place in sterile systems so that bacteria cannot attack the urea.
