A transistor acts as an ampifier, when it operates in active safe. (Yes/No)

A transistor can be used as a switch by operating it in its cut off state or saturation state. (Yes/No)

How is a transistor biased to be in active state?

The rate constant for a first order reaction becomes six times when the temperature is raised from 350 K to 400 K. Calculate activation energy for the reaction.

The rate constant for the first order reactior becomes three times when the temperatur is raised from 20^@ C to 50^@ C. Calculate the energy of activation for the reaction.
