第第1 节 反应速率的定义 一、平均反应速率(Average reaction rate) 定义:单位时间内反应物浓度的减少或生成物浓度的增加表示。单位:mol·dm -3 ·s -1 , mol·dm -3 ·min -1 或或 mol·dm -3 ·h -1 。。 the surroundings 例1、乙酸乙酯的皂化反应 CH 3 COOC 2 H 5 + OH - = CH 3 COO...
第1节 反应速率的定义;Reaction rate: changes in a concentration of a product or a reactant per unit time. ?[ ] concentration Reaction rate = —— ? t;Consider the hypothetical reaction aA + bB ? cC + dD;对于一般的化学反应 aA + bB = gG + hH;二、瞬时反应速率(Instantaneous reaction ...
This paper contributes to the theory of average rate of change (ARC) measurement. We use an axiomatic approach to generalize the conventional ARC measures (such as the difference quotient and the continuously compounded growth rate) in several directions: to outcome variables with arbitrary connected ...
Survey response rate is directly correlated to survey length or duration, we’ve seen on average a 17% drop in response rate when a survey has more than 12 questions or takes longer than 5 minutes to complete. A reminder to complete your survey between 3 to 7 days after the invitation wi...
Although your circumstances may seem similar, your personalized rating factors mean you may pay a different rate than your friends, family and the national average. Still, knowing the average cost of car insurance might give you the information you need to ensure you’re not overpaying for this...

The exponential moving average (EMA) is also weighted toward the most recent prices, but the rate of decrease between one price and its preceding price is not consistent but exponential. Simple Moving Average TheSMAwas more prevalent before the emergence of computers because it is easy ...
rate of chemical reactionA model of mixing with a chemical reaction in a uniform, isotropic turbulent flow has been developed on the basis of the statistical-moments method for calculating the hydrodynamic characteristics of a flow and the probability density function of its mixture coefficient for ...
