The velocity of a reaction is doubled for every 10degree celsius rise in temperature. Ifthe temperature is raised to 50degree celsius,the reaction velocity increases by about

Let the velocity of reaction = x ,

then for every 10 degree rise , the velocity will be the 2 times multiple of x.

So, for 50 degree rise in temperature , the velocity will be doubled by = 50/10 =  5 times

So, the resultant velocity will be = x x 2x 2 x2 x2 x2 = 32 x

Hence, the reaction velocity will be increased by 32 times.
