Reaction rate increases with increasing the substrate (alkyl halide) concentration.
because
Rate of reaction = K [alkyl halide.]
this is unimolecular elimination reaction (E1).
Rate of reaction is directly proportional to concentration of alkyl halide.
this is the elimination reaction as alkene formed.
thus
answer is E1 reaction.
