At constant temperature and volume x decomposes as 2x (g)-3y(g)+2z(g)px is the partial pressure of x. Observation :1,2,3and time(min)0,100,200and px(in mm of Hg):800,400,200.i)What is the order of the reaction with respect to x? ii)Find the rate constant
iii)Find the total pressure when pressure of x is 700mmHg.

The breaking apart of glucose, which involves spontaneous reactions 

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
