Metamorphic rocks are the product of transformation or recrystallization of existing igneous, sedimentary, and metamorphic rocks, due to changes in physical and chemical conditions. Which processes are MOST Likely involved in the transformation of
sedimentary rock to metamorphic rock?

A) weathering and erosion
B) pressure and temperature
C) transport and deposition
D) compaction and cementation

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
