e^(-Keff*t)where [methyl formate](0) is the concentration of methyl formation at the start of the reaction,Keff is the effective constant,and t is time.Prove that the expression above agrees with the rate law and write an expression for Keff of K=0.0233 and the concentration of water....

It should also be noticed that the proportion of water use in service industry showed a dramatic increasing trend, nearly doubled from only 13% in 1997 to 25% in 2023. By contrast, the percentage of water use in household industry and manufacturing industry both fluctuated slightly, ranging fr...
A. the net flux of water is from an area of high solute concentration to an area of low solute concentration B. the net flux of water is from an area of low solute concentration to an area of high solute concentration C. requires a semipermeable process D. is not related to the concen...

and very high pressure is applied to the feed solution to make the activity of the water slightly greater than that in the permeate. This provides an activity gradient across the membrane even though the concentration of water in the product is highe 在逆渗透,渗入是几乎纯净的水在大约1 atm,...
(δ18O values between −7.8‰ and −40.7‰). Recommendations for long-term calibration of CRDS water vapour isotopic analysers were followed40,41. Therefore, our system allows two types of calibration. Firstly, the concentration dependence34,35of the raw isotope measurements is corrected. ...
We arrive at an equation of liquid water content which permits quantitative comparisons between different atmospheric processes of liquid water concentration, some of these being well known for instance the adiabatic cooling, and the radiative coolingothers being mostly disregardedsuch as the turbulent ...
of brine (sale dissolve in water) is 15%. How many gram(s) of salt is needed to make the concentration to 50%? 相关知识点: 试题来源: 解析 140 加入鹽之後,水是不變量,原來水有200×(1−15%)=170克,那麼新鹽水總重量為170÷50%=340克,含鹽340×50%=170克,鹽共加170−200×15%=140...
