Answer:1.
2. The rate constant (k) for the reaction is
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
x = order with respect to
y = order with respect to
n = x+y= Total order
1. a) From trial 1: (1)
From trial 2: (2)
Dividing 2 by 1 :
therefore x=1.
b) From trial 2: (3)
From trial 3: (4)
Dividing 4 by 3:
therefore
2. to find rate constant using trial 1:
