The reaction rate equation of A was found as "–rA = 0.005 CA²
[mol / cm³
min]". According to this,
a) What is the value of the reaction rate and the unit of the rate constant when the output concentration of A is 3 mol / L?
b) If the initial concentration of A is 2 mol / L and its conversion is 80%, what is the reaction rate?
