question54

change in the concentration of a substance per change in time is called rate of a reaction

question 55

Image result for concentration of the reactant


concentration  of H2O(product)




Image result for concentration of the reactant

concentration of H2O2(reactant)

question 56

DATA:

Change in concentration (∆C) = 1.0M-0.5M=0.5M

Change in time (∆T) = 100s-0s= 100s

Average rate=?

SOLUTION:

r= ∆C/∆T

  = 0.5/100

  = 0.005Ms-1
