By equation of continuity Av= constant.
If A is maximum, velocity v would be minimum..
Using Bernoulli's equation we get the pressure as maximum.

Q2

The pressure variation equation of a sound wave propagating in a medium with pressure amplitude P0 is

P=P0 sin ω(t−xv)

Inference:

In the tube where this wave is propagating if we measure pressure, then the maximum pressure measured will be P0 atm and Minimum pressure measured will be −P0 atm as maximum & minimum values of sin θ is (+1/-1).
