Force is the strength or energy as an attribute of physical action or movement. It’s si unit is the Newton
Answer:
The forward reaction is an exothermic reaction.
Explanation:
An exothermic reaction is one in which energy is released, usually in the form of heat hence the enthalpy of the reaction is negative. When a reaction exothermic, the energy of the reactants is greater than the energy of the products hence the excess energy is given out as heat. The reactants lie at a higher energy level in the reaction profile compared to the products.
When we look at the reaction given in the question, NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ , we can easily see from the thermochemical reaction that the forward reaction is exothermic, energy is released by the reaction system as evidenced by the negative enthalpy of reaction.
Answer:
Here's what I get.
Explanation:
1. Write the chemical equation

Assume that we start with 4 L of HCl
2. Calculate the theoretical volume of oxygen

3. Add 35% excess

4. Calculate the theoretical volume of nitrogen

4. Calculate volumes of reactant used up
Only 85 % of the HCl is converted.
We can summarize the volumes in an ICE table
4HCl + O₂ + N₂ → 2Cl₂ + 2H₂O
I/L: 4 1.35 5.08 0 0
C/L: -0.85(4) -0.85(1) 0 +0.85(2) +0.85(2)
E/L: 0.60 0.50 5.08 1.70 1.70
5. Calculate the mole fractions of each gas in the product stream
Total volume = (0.60 + 0.50 + 5.08 + 1.70 + 1.70) L = 9.58 L

1. 0+15+30+45+60=150/5=30 s
0+10+16+22+27=75/5=15 cm^3
then, 15/30= 0.5 cm^3/s(average rate of rxn)
2. 0+15+30+45+60+75+90+105+120=540/9=60 s
0+10+16+22+27+31.50+36+39.5+42=224/9=24.89cm^3
then, 24.89/60=0.414cm^3/s (avrg rate of rxn)
3. overall rxn add all the time divide by 12 and the volume add them too and divide by 12. after take average volume divide by the average time to get the average rate of overall rxn
4. 16/30= 0.533cm^3/s
5. 39.5/105= 0.37cm^3/s
