Which of the following are features of transition state theory? Select all that apply. ? The enzyme only binds the transition state, and cannot bind the substrate. ? The free energy of Activation is a measurement of the change in energy between the transition state and the ground state of the reactants. Transition state theory describes how enzymes increase the rates of reactions. An enzyme lowers the Gibbs free energy.

(b) R P \frac{1}{4}l 30° Q l FIGURE 1 FIGURE 1 shows a uniform rod PQ of weight 50 N and length \(l\) is hinged at a wall at one end P, and the other end Q is supported by a thin wire QR. The wire makes an angle 30° with the horizontal. An object of mass 1.5 kg is placed on the rod at a distance of \(\frac{1}{4}l\) from P. Calculate, (i) the tension T in the wire (ii) the horizontal component of the force at end P (iii) the vertical component of the force at end P of the rod (iv) the magnitude force at end P of the rod.
