How do you find instantaneous rate of reaction?
We determine an instantaneous rate at time t:
- by calculating the negative of the slope of the curve of concentration of a reactant versus time at time t.
- by calculating the slope of the curve of concentration of a product versus time at time t.
What is instantaneous reaction with example?
1) Instantaneous reaction: Those reactions which occur in very very short period of time (say 10−13 to 10−16sec) is called instantaneous reaction. Any ionic reactions are the example of in- stantaneous reaction.
What difference is there between the instantaneous and average rate of reaction?
The main difference between instantaneous rate and average rate is that the instantaneous rate measures the change in concentration of reactants or products during a known time period whereas average rate measures the change in concentration of reactants or products during the whole time take for the completion of the …
What is formula for rate of reaction?
Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.
What is the instantaneous rate of the reaction at T 800 ST 800 S?
The answer is rate= 6.8×10^-5 m/s……

How do you find instantaneous rate of change on a graph?
To find the instantaneous rate of change using a graph, draw a line that only touches the graph at one point, known as a tangent line. Then find the slope of the tangent line to calculate the instantaneous rate of change.
What is average rate of reaction?
The average rate of reaction is defined as the ratio of the change in the concentration of the reactants or the products of a chemical reaction to the time interval.
What is the instantaneous rate of the reaction at T 800 S?
OneClass: What is the instantaneous rate of the reaction at t=800s? The answer is rate= 6.8×10^-5 m/s…
Why is instantaneous rate better than average?
Why is instantaneous rate preferred over average rate of reaction? The rate of reaction at any time depends upon one of the reactants at that time which is not constant but goes on decreasing with time continuously. Therefore, instantaneously rate gives more correct information at that time as compared to average rate.
What is rate of reaction Class 12?
Rate of a chemical reaction IS the change in the concentration of any one of the reactants or products per unit time. It is expressed in mol L-1 s-1 or Ms-1 or atm time-1 units. Rate of reaction. = (decrease/increase in the concentration of reactant/product/time taken)
What is the equilibrium constant KC?
The equilibrium constant, Kc, is the ratio of the equilibrium concentrations of products over the equilibrium concentrations of reactants each raised to the power of their stoichiometric coefficients.
What is the order of the reaction?
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant. This is distinct from the molecularity (or stoichiometry) of the reaction which is the theoretical integer value of the number of molecules involved in the reaction.
