To enhance the effective surface, and hence the chemical reaction rate, catalytic surfaces often take the form of porous solids.
One such solid may be visualized as consisting of a larger number of cylindrical pores, each of diameter D and length L.
Consider conditions involving a gaseous mixture of A and B for which species A is chemically consumed at the catalytic surface. The reaction is known to be first order k1CA. Under steady state, flow over the porous solid is known to maintain a fixed value of the molar concentration CA0 at the pore mouth.
Beginning from fundamentals, obtain the differential equation that governs the variation of CA with distance x along the pore. Applying appropriate boundary conditions, solve the equation to obtain an expression for CA(x).

Answer:
THE RUBBER BALL
Explanation:
From the question we are told that
The mass of the rubber ball is
The initial speed of the rubber ball is
The final speed at which it bounces bank
The mass of the clay ball is
The initial speed of the clay ball is
The final speed of the clay ball is
Generally Impulse is mathematically represented as
where is the change in the linear momentum so
For the rubber is
=>
For the clay ball
=>
So from the above calculation the ball with the a higher magnitude of impulse is the rubber ball
