Answer:
b) O2, because it has weaker intermolecular forces
Explanation:
The preassure is produced by the collisions of the gas molecules with the walls of its container.
When the intermolecular forces between the gas molecules increase, those molecules start to "slow down" by effect of the interactions. The collisions decrease in frequency and intensity producing a smaller preassure in the container.
Both O2 and Cl2 are non-polar gases and the only intermolecular forces they have are the London ones. Given that the O2 molecules are smaller than the Cl2, the last ones attract each other with more strengh.
Being all that said, the container with the oxygen is expected to have a higher preassure.
Answer:
Rate law is: Rate = k[NO2]^2 = 10 x [NO2]^2
When [NO2] = 0.200 M:
Rate = 10 x 0.200^2 = 0.400 M/s
When [NO2] = 0.100 M:
Rate = 10 x 0.100^2 = 0.100 M/s
When [NO2] = 0.050 M:
Rate = 10 x 0.050^2 = 0.0250 M/s
Explanation:
If you used the method of initial rates to obtain the order for no2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 m, 0.100 m, & 0.050 m no2.
Rate law is: Rate = k[NO2]^2 = 10 x [NO2]^2
When [NO2] = 0.200 M:
Rate = 10 x 0.200^2 = 0.400 M/s
When [NO2] = 0.100 M:
Rate = 10 x 0.100^2 = 0.100 M/s
When [NO2] = 0.050 M:
Rate = 10 x 0.050^2 = 0.0250 M/s
The values of N, log N and ln N are all worked out below.
We have the number N as 8.99
hence;
1) lnN = ln(8.99) = 2.196
log N = log (8.99) = 0.954
2) If we have ln N as 3.949
N = e^3.949 = 51.88
So;
log N = log (51.88) = 1.715
3) log N = 0.134
N = Antilog (0.134 ) = 1.36
ln N = ln (1.36) = 0.307

Answer:
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
