1.what term best describes the measure of the increase in the concentration of a product per unit time?

A)activation energy
C)reaction rate
D)reaction time

2. In the following equation, which of the reactants that is a bronsted-lowry acid HCN+H20-->H30+ + CN

I think either c or d
What about you?

The reaction rate is the increase in concentration per unit of time.
For #2, remember a Bronsted acid is a proton donor. Which substance on the left is donating protons?

so #1 is c
#2- is it water(H2O)

#1 is c.
It appears to me that H2O is receiving a proton to become H3O^+? Is that not right?
