According to the decomposition of XY is second order, and we assume that the rate constant (K) = 6.92 X 10^-3 M^-1 :
So according to this formula:
Kt= 1/[XY]t - 1/[XY]o
when [XY]o is the initial concentration = 0.1 m & [XY]t is the concentration after passing a period of time= 0.1 x 0.125 = 0.0125 m
and when K= 6.92X10^-3 M^-1
By substitution:
t = (1/[XY]t - 1/[XY]o) / K
=(1/0.0125 - 1/0.1) / 6.92X10^-3
∴t = 1011 S = 17 min
Number of moles:
n = M x V
n = 0.002915 x 1.25
n = 0.00364375 moles
Light energy used for photosynthesis is absorbed by chlorophyll <span>found in plant cells. Chlorophyll, the green substance found in a plant's chloroplasts, is what gives the plant its pigmentation. It is also the one that absorbs light energy in order for photosynthesis to proceed. Light energy converts CO2 and water into glucose, the food used by plants.</span>
