Answer:
Reference frame can be defined as from the perspective of an individual to tell if an object is moving.
Example:
Eienstien used a reference frame in his train thought experiment.
Answer:
The statement 'If the reactions of A⟶D are rearranged, they become non spontaneous.' is false
Explanation:
Step 1: Data given
Reaction 1 (A⟶B) has a ΔG=+3 kJ/mol
Reaction 2 (B⟶C) has a ΔG=−6kJ/mol
Reaction 3 (C⟶D) has a ΔG=+1 kJ/ mol.
Step 2:
To be spontaneous ΔG should be negative (ΔG<0)
For reaction A⟶D; ΔG = 3kJ/mol -6kJ/mol + 1 kJ/mol = -2 kJ/mol
This means for the reaction A⟶D; the reaction is spontaneous
This means for the reaction D⟶A; ΔG = 2kJ/mol, so the reaction is non-spontaneous
For reaction 1 and 3 the reaction is ,non-spontaneous (but the reverse reaction is). Reaction 2 is driving reactions 1 and 3 forward. A⟶D is thermodynamically spontaneous.
The statement 'If the reactions of A⟶D are rearranged, they become non spontaneous.' is false
Answer:
Which statement is true about the particles of a solid when the solid changes into a liquid? (5 points)
a. They stop vibrating.
Selected: b. Their kinetic energy increases. This answer is correct.
c. They move closer to each other.
d. The attractive force between them increases.
Explanation: when a solid turns to a liquid it means it was melted and it needs to be heated to melt meaning the kinetic energy increases because the solid was heated up. Also this was on my test and i got it right so yeah.
