To determine the k for the second condition, we use the Arrhenius equation which relates the rates of reaction at different temperatures. We do as follows:
ln k1/k2 = E / R (1/T2 - 1/T1) where E is the activation energy and R universal gas constant.
ln 1.80x10^-2 / k2 = 80000 / 8.314 ( 1/723.15 - 1/593.15)
k2 = 0.3325 L / mol-s
Sound is made when air molecules. Vibrate and move in a wave pattern, so sound moves in waves of compressions and refractions (expansion).
Hope this helps! :)

One difference between strong bases and weak bases is that a strong bases dissociate completely while weak bases do not. A strong base is a compound that completely ionizes into metal and hydroxide ions when in a solution, on the other hand weak bases only partially ionizes to metal and hydroxide ions in solution. An example of a weak base is ammonia and an example of a strong base is sodium hydroxide.
