Okay, so i see that you need help with this question, and it says, assess the following statement for accuracy.
00:04
The reactions a plus b is greater than or equal to c will spontaneously proceed forward if the free energy of a plus b is 30 units and the free energy of c is 25 units.
00:21
Select one.
00:22
So first of all, you need to understand the concept of free energy in chemical reactions.
00:40
Okay, that's supposed to be an a.
00:43
Free energy often denoted as g for gibbs free energy is a thermodynamic quantity that can be used to predict the direction of a chemical reaction.
00:56
To predict the direction of the chemical reaction.
01:11
If the change to free energy is negative, the reaction will tend to proceed spontaneously in the forward direction.
01:20
If it's positive, then the reaction is non -spontaneous and will not proceed without input of energy.
01:28
So to calculate the change in free energy for a reaction to determine whether the reaction is a plus b is greater than or equal to c will provide a spontaneous reaction, we need to calculate the change in free energy...
