At 100 K, a reaction is `30%` complete in 10 minutes, while at 200 K, 30% is complete in 5 minutes . The activation energy of the reaction is :

At 300K, a certain reaction is 50% complete in 20 minutes. At 350K, the same reaction is 50% complete in 5 minutes. Calcualte the activation energy for the reaction.

A first order reaction is 50% completed in 20 minutes at 27°C and in 5 minutes at 47°C. The energy of activation of the reaction is :

A first order reaction is 50% completed in 30 minutes at 300 K and in 10 minutes at 320 K, Calculate the activation energy of the reaction (R = 8.314 "JK mol"^(-1) .)

A first order reaction is 50% completed in 20 minutes at 27^(@) C and in 5 minutes at 47^(@) . The energy of activation of the reaction is :

A certain reactions is 50% complete in 20 minutes at 300 K and the same reaction is again 50% completely in 5 minutes at 350 K. Calculate the activation energy if the reactions is of first order.

50% of a reaction is completed in 20 minutes and 75% is completed in 30 minutes from the beginning.What is the order of reaction
