reactivity - Why are silyl chlorides more readily hydrolysed than alkyl chlorides?

I know that the $\ce{Si-Cl}$ bond has a slightly higher energy, but silyl chlorides are much more readily hydrolyzed compared to alkyl chlorides. I do not fully understand why that is. My thoughts so far are:

• 
  

  There is a better match in energy between the orbitals of the $\ce{Si-Cl}$ bond and water.

  
  


• 
  

  Reactions proceed when there is a favorable interaction between HOMO and LUMO.

  
  


• 
  

  In this case, the HOMO is the lone pair on the water molecule. The LUMO of a $\ce{Si-Cl}$ bond is closer to it in energy compared to a $\ce{C-Cl}$ bond.

  
  

Is this the right argument to take?
