A foreign substance that increase the speed of a chemical reaction is called
Catalyst: Substances which alter the rate of a chemical reaction and themselves remain chemically and quantitatively unchanged after the reaction are known as catalysts and the phenomenon is known as catalysis.
. What will be the value of instantaneous rate of reaction from the graph?
If you make a graph of concentration of reactant vs time, the instantaneous reaction rate at a given time is the slope of the tangent line at that point in time. It is also the value of the rate law at a specific concentration (dA/dt is rate = k [A]).
The rate of a chemical reaction doubles for every 10°C rise of temperature. If the temperature is raised by 50°C, the rate of the reaction increases by about
and for 10times=50°c.
For every 10°C rise of temperature, the rate is doubled. Thus, the temperature coefficient of the reaction = 2
When temperature is increased by 50°, rate becomes =2(50/10) = 25 times = 32 times
Chemical substances speeding up rate of chemical reaction is called as
Chemical substances speeding up the rate of chemical reaction is called as
The rate constant of zero-order reactions has the unit
For the reaction A + B → C+ D . The variation of the concentration of the products is given by curve
For the reaction, A+B⟶C+D, the variation of the concentration of the products is given by the curve Y.
Initially, the product concentration is 0, then it gradually rises and reaches a maximum value. After that it remains constant.
This behavior is represented by the curve Y.
The term -dx/dt in the rate expression refers to the:
