Rate of Weathering in historic cemeteries, slate tombstones from the 1700s are less weathered than marble tombstones from the 1800s. Why? Some kinds of rocks weather more rapidly than others. The rate at which weathering occurs is determined by the type of rock and the climate.
Type of Rock
Rocks wear down slowly If they are made of minerals that do not dissolve easily. Rocks weather faster If they are made of minerals that dissolve easily.
Some rocks weather more easily because they are permeable A permeable (PUR mee uh bul) material is full of tiny air spaces. The spaces Increase the surface area. As water seeps through the spaces in the rock, It carries chemicals that dissolve the rock and removes material broken down by weathering
Climate
Climate is the average weather conditions in an area. Weathering occurs faster in wet climates. Rainfall causes chemical changes. Freezing and thawing cause mechanical changes in cold and wet climates. Chemical reactions occur faster at higher temperatures. That is why chemical weathering occurs more quickly where the climate is both hot and wet. Human activities, such as those that produce acid rain, also increase the rate of weathering​

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.
