The forward rate constant for the elementary reversible gaseous reaction
`C_(2)H_(6)ltimplies2CH_(3) "is" 1.57xx10^(-3)s^(-1)at 100 K`
What is the rate constant for the backward reaction at this temperature if `10^(-4)` moles of `CH_(3)` and 10 moles of `C_(2)H_(6)` are present in a 10 litre vessel at equilibrium .
a) `1.57xx10^(9) L "mole"^(-1)s^(-1)`
b) `1.57xx10^(10) L "mole"^(-1)s^(-1)`
c) `1.57xx10^(11) L "mole"^(-1)s^(-1)`
d) `1.57xx10^(7) L "mole"^(-1)s^(-1)`

Options

A. `1.57xx10^(9) L "mole"^(-1)s^(-1)`
