Question

A solution of starch at room
temperature does not
readily decompose to form a
solution of simple sugars
because:
O a. starch hydrolysis is
nonspontaneous
O b. starch cannot be
hydrolyzed in the
presence of so much
water
e c. the activation energy
barrier for this reaction
cannot be overcome
o d. the starch solution has
less free energy than
the sugar solution
e. the hydrolysis of starch
to sugar is endergonic
