Instantaneous reaction rate equation

NettetThe rate at any time is equal to the negative of the slope of a line tangent to the curve at that time. Tangents are shown at t = 0 h (“initial rate”) and at t = 12 h (“instantaneous rate” at 12 h). Relative Rates of Reaction The rate of a reaction may be expressed as the change in concentration of any reactant or product. NettetRate equation [ edit] For a chemical reaction a A + b B → p P + q Q, the rate equation or rate law is a mathematical expression used in chemical kinetics to link the rate of a …

NettetThe general form of an equation in point-slope form is y - y1 = m (x - x1) where m is the slope and (x1,y1) is the point. Our point is (7,109.45) and the slope is the average slope between [6.5,7.5] which is 1.9. Plug these into the equation and you get an approximation of the equation of a tangent line at (7,109.45). 2 comments ( 2 votes) Cara Nettetinstantaneous rate of a chemical reaction at t = 0 s (immediately after the reaction has begun) instantaneous rate rate of a chemical reaction at …

NettetThe instantaneous rate of a reaction at “time zero,” when the reaction commences, is its initial rate. Consider the analogy of a car slowing down as it approaches a stop sign. The vehicle’s initial rate—analogous to the beginning of a chemical reaction—would be the speedometer reading at the moment the driver begins pressing the brakes ( t 0 ). Nettet-Instantaneous rate is calculated by finding the slope of a tangent to the curve of concentration versus time at any point on the curve. Select all the options that correctly express the rate of the given reaction in terms of reactant and product concentrations. 2ClO (g) → Cl2 (g) + O2 (g) -rate = Δ [Cl2]/Δt -rate = - 1/2 Δ [ClO]/Δt
