What change would you expect on the rate of the sn2 reaction of 1-iodo-2-methylbutane with cyanide ion if the nucleophile concentration is halved and the alkyl halide concentration is unchanged ?

Rate of reaction will be half of it's initial value

Explanation:

For the given reaction, the rate law is -

Where k is rate constant, [1-iodo-2-methylbutane] is concentration of 1-iodo-2-methylbutane and is concentration of

Here nucleophile is the ion

Initiallly,

When concentration of is halved then-

So rate of reaction will be half of it's initial value

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
