Answer: The rate will increase by a factor of 9.
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.
Given: Order with respect to = 2
Order with respect to = 1
Thus rate law is:
k= rate constant
It is given that the initial concentration of NO is tripled while all other factors stayed the same
Thus the rate will increase by a factor of 9.
Explanation:
The given reaction at cathode will be as follows.
At cathode: , = -0.761 V
At anode: , = 0.761
Therefore, net reaction equation will be as follows.
Initial: 0.129 - - 0.427
Change: -0.047 - - -0.047
Equilibrium: (0.129 - 0.047) (0.427 - 0.047)
= 0.082 = 0.38
As for the given reaction is zero.
Hence, equation for calculating new cell potential will be as follows.
E_{cell} =
=
= 0.019
Thus, we can conclude that the cell potential of the given cell is 0.019.

If the pressure increases to 300 KPa and the volume remain constant the temperature will be
900K
it is calculated using the gays lussac law formula that is P1/T1=P2/T2
P1= 100Kpa
p2=300Kpa
T1=300k
T2=?
by making T2 the subject of the formula T2 =P2T1/P1
=300KPa x300 k/100 kpa = 900 K
Answer:
The unit of A must be 'atm', and the units of B and C must be 'atmxK'.
If a system is at steady state it means the properties do not vary over time.
Explanation:
The units of pressure must be atm, bar, Pa or mmHg. If we use the atm unit the result of the equation should be the pressure in 'atm'. Thus, the unit of A must be 'atm', and the units of B and C must be 'atmxK'. So, If we replace the equation with the temperatures (T) in Kelvin (K) the result will be in 'atm'.
Problem 2: If a system is at steady state it means the properties do not vary over time. This is the definition of a steady state. Also, every particular steady state will define their own properties but each steady state will no vary their properties over time.
