AI Thread Summary
The discussion focuses on calculating the energy dynamics in beef cattle pasture production, specifically regarding the albedo of leaves. Key calculations include determining the percentage of solar energy trapped by plants through photosynthesis, the energy available to cattle from consumed plants, and the albedo of leaves. The total annual solar energy received is 2,093,400 kJ, with specific energy values for reflection, evaporation, and plant use provided. Participants seek assistance with the formulas needed to derive these values. Accurate calculations are essential for understanding pasture productivity and its implications for cattle farming.

k I am stuck on this one question i don't know the formulas can anyone help me with each and tell me how to do it!

heres teh question:
the prodcution of some beefe cattle in AB is based on fertilized fields of rye grass and clover. a typical sq. metre of pasture receives 2093400kJ of visible light energy from the sun each year. The energy is accounted for as followed:

energy is reflected by le aves 330 004kj
energy is lost by evaporation of water 1046700kj
energy transmitted to teh ground
energy trapped by plants 42872kj
trapped by eenergy used in teh lpant respiration 3936

1- what % of total avaliable solar energy is trapped by the plants through photosynthesis over the yer?
2-how much energy is avaliable to cattle from each sq metre if they eat all teh plants
3-what is the albedo of the leaves?

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
