(a) What is the physical significance of energy of activation ? Explain with diagram.(b) In general, it is observed that the rate of a chemical reaction doubles with every 10 degree rise in temperature. If the generalization holds good for the reaction in the temperature range of 295 K to 305 K, what would be the value of activation energy for this reaction ?[R = 8.314 J mol-1 K-1]
Q1// In an attempt to understand the mechanism of the depolarization process in a fuel cell, an
electro-kinetic model for mixed oxygen-methanol current on platinum was developed in the
laboratory at FAMU. A very simplified model of the reaction developed suggests a functional
relation in an integral form. To find the time required for 50% of the oxygen to be consumed, the
time, T is given by:

√X² +4
Use Simpson's 3/8 multiple segment rule with 6 segments to find the time required for 50% of the
oxygen to be consumed.
