When a hot body warms a cool one are their temperature changes equal in magnitude ?

The rate of a particular reaction triples when temperature changes from 60°C to 100°C. Calculate the activation energy of the reaction.

The rate of a reaction becomes four times when the temperature changes from 293 K to 313 K. Calculate the energy of the activation (E_a) of the reaction assuming that it does not change with temperature. [R=8.314" JK"^(-1)" mol"^(-1), log 4 = 0.6021]

The rate of reaction is doubled when the temperature changes from 27^@C to 37^@C . Calculate the energy of activation.

If the temperature of a body falls by 1^@C , What will be the change in temperature in Kelvin scale.

Characterize each of the following as beiing as being TRUE or FALSE, If the statement is false, change the word or phrase in such a manner as to make the statement true Oogenesis results in the formation of one egg and three polar bodies from one meiotic division.

Show that the efficiency of all reversible engines working between the some two temperatures depends only on the temperature of hot and cold bodies.

A body is acted upon simultaneously by two vectors one of 30 magnitude and the other of 40 magnitude at right angle to each other .Find the magnitude and direction of resultant vector.

Calculate the entropy change involved in the conversion of one mole of water at 373 K to vapour at the same temperature.(Latent heat of vaporisation of water at this temperature , Delta H_vap = 2.257 kJg^-1 )
