A substance which retards the rate of a reaction is called: Inhibitor
With increase in 10°C temperature, the rate of reaction double. This increase in rate of reaction is due to: Increase in number of effect collisions
After 3 half lives of a chemical reaction, the % fraction of the amount left is: 12.5
The power of which the concentration of a substance appears in the rate expression is known as: order of reaction with respect to that substance
The unit of rate constant depends upon: Order of reaction
The unit of rate constant is same as that of rate of reaction in: Zero order reaction
The mathematical relation between the rate of reaction and the concentrations of the reactants is known as the: Rate law
If the energy of the activated complex lies close to energy of reactants, it means that reaction is: Fast
Velocity constant is the rate of reaction when the concentrations of reactants are: Unity
When a reaction proceeds in a sequence of steps, the overall rate is determined by: Slowest step
In zero order reaction, the rate is independent of: Concentration of reactants
The rate of reaction: Decreases as the reaction proceeds
The true representation for the units of rate constant K for the first order reaction: sec-1
The influence of temperature on reaction rate is predicated by: Arrhenius equation
The reaction that involves gases, its rate does not depend upon: Moles dm-3
