Answer:
The answer is b. The number of collisions of gas particles increases
Answer:
C. The reaction is energetically favorable.
Explanation:
The reaction which shows the removal of the terminal phosphate from the ATP is shown below:
The Gibbs' free energy change of this reaction, 
Hence, Option A is not correct.
It is a type of hydrolysis reaction in which water is being added to the molecule.
Hence, Option B is not correct.
The Gibbs' free energy change is negative which means that the reaction is energetically favorable.
Option C is correct.

The question is incomplete, the complete question is;
Zinc and sulfur react to form zinc sulfide by the equation shown below. How many grams of ZnS can be formed when 12.0 g of Zn reacts with 6.50 g of S? (Atomic mass: Zn = 65.38, S = 32.06).
Answer:
17.5 g of ZNS
Explanation:
The equation of the reaction is;
Zn(s) + S(s) ------->ZnS(s)
Number of moles of Zn = 12.0/65.38 = 0.18 moles
Number of moles of S = 6.50/32.06 = 0.20 moles
Hence Zn is the limiting reactant
If 1 mole of Zn yields 1 mole of ZnS
Then 0.18 moles of Zn also yields 0.18 moles of ZnS
Mass of ZnS produced = 0.18 moles * 97.44 g/mol = 17.5 g of ZNS
0.2M means 0.2mol CaCl2/1L solution.
This question didn't give us a density of the solution so needs an assumption that the solution has equal volume to water.
xmol/0.5L=0.2M
x = 0.1
0.1mol of CaCl2 is needed. Ca=40g/mol, Cl=35.5g/mol.
CaCl2 0.1mol = (40+35.5*2)*0.1=11.1g
