#3 of thermo terms
Evgesh-ka [11]

Answer:

C

Explanation:

If the enthalpy change (i.e. Δ<em>H</em>) of a reaction is negative, then the reaction releases heat and is hence exothermic.

Hence, our answer is C.

Conversely, if Δ<em>H</em> is positive, the reaction absorbs heat and is endothermic.

Δ<em>H</em> tells us nothing about the speed of the reaction.

While Δ<em>H</em> influences free-energy change (Δ<em>G</em> = Δ<em>H</em> - <em>T</em>Δ<em>S</em>), we cannot predict the sign of Δ<em>G</em> given only Δ<em>H </em>(recall that a reaction is spontaneous if Δ<em>G</em> < 0).

explain what happens if high pressure is implemented on the equilibrium reaction . State your observations for both rate of reac
amm1812
The equilibrium position will shift in order to counterbalance the change. That means the equilibrium position will shift, lowering the pressure once more.... When the pressure on a gas reaction is increased, the equilibrium moves to the side with fewer molecules.

To find the molecular formula from the empirical formula, one must determine the compounds _____
xxTIMURxx [149]

Answer:

Relative molecular of the compound or infomation like vapour density, volume occupied by a known mass of its vapour at stp, etc

Explanation:

The molecular mass of a compound is twice its vapour density. We can find the molecular formula using the relationship below:

  •    Empirical formula is the simplest formula of a compound. It repeats itself "n" times to become a molecular formula i.e (EF)ₙ = MF...... n is the number of times the empirical formula presents in a mole of the compound.
  • Most times, n is a whole number like 1,2,3,.....
