Answer:
An increase in temperature typically increases the rate of reaction because an increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Answer:
The answer to your question is letter b) He and Ne
Explanation:
Elements that have similar properties are placed in the same group in the periodic table.
So
A C and F These elements do not have similar properties because C is in group 4A and F is in group 7A. This is not the right answer.
B He and Ne These elements have similar properties becase they are in the same group (8A).
C Al and Si These elements do not have similar properties because Al is in group 3A and Si is in group 4A. This is not the right answer.
D N and S These elements do not have similar properties because N is in group 5A and S is in group 6A. This is not the right answer.
Answer:
Yes, the given instance is an example of a trade-off.
Explanation:
- The trade-off seems to be a strategy to minimize or surrender one or more favorable results in consideration for increasing either receiving other favorable results to optimize cumulative benefit or efficacy within such conditions.
- The above is indeed a trade-off since the participants are experimenting in exchange again for ice cream individuals have to enjoy. The ice cream manufacturer always gets a review of the technician in exchange for free ice cream.
Answer:
2 NO (g) → N2 (g) + O2 (g)
2 NOCl (g) → 2 NO (g) + Cl2 (g)
____________________________
2NOCl (g) ⟶ N2 (g) + O2 (g) + Cl2 (g)
ΔH = [90.3 kJ x 2 x -1] + [-38.6 kJ x -1 x 2] = -103.4 kJ
The ΔH for the reaction is -103.4 kJ
