Consider the Arrhenius equation given below and mark the correct option. k=A e^(-E_(a)//RT)

Answer»

Rate constant INCREASES exponentially with increasing ACTIVATION energy and decreasing TEMPERATURE.
Rate constant decreases exponentially with increasing activation energy and decreasing temperature.
Rate constant increase exponentially with decreasing activation energy and decreasing temperature.
Rate constant increases exponentially with decreasing activation energy and increasing temperature.

Solution :Arrhenius EQUATION:
`k=A e^(-E_(a)//RT)`
`therefore k PROP e^(-1//T)` and `kprop e^(e^(-E_(a)))`
`therefore k prop T`
`therefore` Rate constant increases exponentialy with decreasing activation energy and increasing temperature.
