Answer:
LiF has the highest melting point.
Reason: If we compare the bond length of the molecules we find that LiF has the shortest bond length due to the fact that F is smallest out of F, Cl, Br, I. As the bond is very short the bond is stronger and hence we need to provide much more energy to break the bond. Hence a higher boiling point.
Hi there,
My answer would be False.
Please mark
Thanks
Answer:
28.43 min
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = min⁻¹
Initial concentration = 0.1 M
Final concentration = M
Time = ?
Applying in the above equation, we get that:-
