The answer is; C

There are 2 Carbons, 4 Hydrogens, and 6 oxygens  on both sides

All the moles of the elements on the right of the reaction equation are balanced with those on the left of the equation. These moles are indicated by the number in front  of the symbols of the elements. This ensures that the first law of thermodynamics is observed. This law states that no matter or energy can be destroyed or created; It can only be transformed.

Yes, it will be worthwhile to investigate finding a catalyst to use in this reaction under standard conditions because it is negative.

<h3>What is a Catalyst?</h3>

This is a substance which speeds up the rate of a chemical reaction by lowering the activation energy.

ΔG being negative indicates a a slow reaction which is why a catalyst under standard conditions should be used.

c) No, because Celsius is not an absolute temperature scale

Explanation:

converting  5 oC to kelvin which is the absolute temperature scale gives = 273 + 5 = 278 K

and converting 20 oC to kelvin = 20 + 273 = 293 K

the ratio = 278 / 293 = 0.94 approx 1 not 4
