Question

For a certain reaction large fraction of molecules
has energy more than the threshold energy yet
the rate of reaction is very slow, Why?
​

Answer 1

HEY BUDDY ♥♥♥

HERE IS THE ANSWER ✌♥

⤵⤵⤵⤵⤵

Though the reacting molecules may be having energy more than threshold energy , yet they may not be effective due to lack of proper orientation .

Answer:

Energy and orientation of molecules are the key factors that determine the rate of reaction .

So if any one of them is lacking the rate of reaction will not be high enough .

Therefore , if in a certain reaction large fraction of molecules has energy more than the threshold energy yet the rate of reaction is very slow, this may happen due to absence of proper orientation of molecules .
