Question

Among the following graphs showing variation of rate constant with temperature (T) for a reaction, the one that exhibits Arrhenius behavior over the entire temperature range is ......

(d) both (b) and (c)

Answer 1

k = \(Ae^-{\Big(\frac {E_a}{RT}\Big)}\)

In k = In A – \(\Big(\frac {E_a}{R}\Big)\) \(\Big(\frac{1}{T}\Big)\)

this equation is in the form of a straight line equation y = c + m x 

a plot of ink vs \(\Big(\frac{1}{T}\Big)\) is a straight line with negative slope.
