|
A.
A particular chemical reaction is more temperature sensitive at low temperatures |
|
B.
A very high value of equilibrium constant, K (K >> 1) indicates that the reaction is practically irreversible in nature |
|
C.
The intercept of the Arrhenious plot is called the 'activation energy' |
|
D.
Non-ideal flow takes place in reactors due to recycling, channeling or by creation of stagnant regions |
