Answer:
a. first-order in both A and B.
Explanation:
In order to determine the kinetics of reaction let us consider the given data
a) Doubling the concentration of B while keeping the concentration of A fixed doubles the rate of the reaction. : it means the reaction is first order reaction with respect to reactant B.
b) The half life is the time required to complete the reaction by half way.
As with time one half of A remains and after equal time one fourth of A remains it means again the order of reaction is first with respect to A also.
There is no effect on the half life if we are decreasing the initial concentration of A also.
Well, I know one. A positive: decreasing pollution because most people are in quarantine and not outside.
Answer:
See explanation
Explanation:
CO2 reacts with water to form carbonic acid as follows;
CO2(g) + H2O(l) ---------> H2CO3(aq)
This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.
Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.
The scientific method is defined as a method of research in which a problem is identified, relevant data is gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested.
