Answer:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
Overall Rate = k1[H2] [ICl]
Explanation:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
The overall reaction is the sum of the two two reactions shown in the question. After the two reactions are summed up properly, this overall reaction equation his obtained.
Since K1<<K2 it means that step 1 is slower than step 2. Recall that the rate if reaction depends on the slowest step of the reaction. Hence
Overall Rate = k1[H2] [ICl]
Answer:
1.42m/s
Explanation:
velocity=displacement/time
v=50/35=1.42m/s
Answer should be 20% so 1/5
Answer:
True
Explanation:
<u>The first law of thermodynamics</u> establishes a relationship between the internal energy of the system and the energy that it exchanges with the environment in the form of heat or work.
The first law of thermodynamics determines that the internal energy of a system increases when heat is transferred or work is done on it.
Like all the principles of thermodynamics, the first principle is based on systems in equilibrium.
On the other hand, it is likely that you have heard more than once that energy is neither created nor destroyed, only transformed. It is the general principle of energy conservation. Well, the first law of thermodynamics is the application to thermal processes of this principle.
The universe as a whole could be considered an isolated system, and therefore its total energy remains constant.
