Question

# For which of the following reaction $$k_{310}/k_{300}$$ would be maximum ?

A
P+QR;Ea=10kJ
B
E+FD;Ea=21kJ
C
A+BC;Ea=10.5kJ
D
L+MN;Ea=5kJ

Solution

## The correct option is B $$E\, +\, F\, \rightarrow\, D;\, E_a\, =\, 21\, kJ$$$$k_{310}\, >\, k_{300}$$, and $$k\, \propto\, \displaystyle \frac {1}{E_a}$$ and also $$E_a\, \propto\, \displaystyle \frac {1}{T}$$But $$E_a$$ at $$310\, K\, <\, E_a$$ at $$300K$$$$\therefore\, k_{310}/k_{300}$$ will be maximum for the reaction having high $$E_a$$$$E\, +\, F\, \rightarrow\, D;\, E_a\, =\, 21\, kJ$$Chemistry
