The one you have selected is correct. CO is a compound because it contains more than one element.
½H2(g) + ½I2(g) → HI(g) ΔH = +6.2 kcal/mol
or...
½H2(g) + ½I2(g) + 6,2kcal/mole → HI(g)
________
21.0 kcal/mole + C(s) + 2S(s) → CS2(l)
or...
C(s) + 2S(s) → CS2(l) ΔH = +2,1 kcal/mole
_________
ΔH > 0 ----------->>> ENDOTHERMIC REACTIONS
An increase in the temperature will speed up the reaction by increasing the frequency and efficiency of the collisions of molecules.
Answer:
C
Explanation:
Pressure it says it in the name its the force of colliding particles
If the temperature rises in a reaction. Exothermic is if it loses heat.
