The enthalpy change is negative.
The other statements are false because:
Can take place without a catalyst
Energy is given out to the surroundings.
Kinetic energy of products is higher.
Answer:
COCl species is an intermediate in the mechanism.
Explanation:
Intermediates are those chemical species which only appears for a short time in a course of a chemical reaction. They act as product and reactant during the reaction. Also they do not appear in overall chemical reaction.
Step 1: 
Step 2: 
Step 3: 
Overall reaction :
As we can see that all the chemicals are present in the overall reaction beside COCl.
COCl species is an intermediate in the mechanism.
Hey there,
Your question states: Why is ice less dense than liquid water?

Hope this helps.

Answer:
The answer is 4778.4 cm (cubed)
Explanation:
V = (πr(squared)) x (h/3)
V = (π x 13(squared)) x (27/3)
V = 530.9291585 x 9
V = 4778.4
