Question 1 Your company is considering to buy a new enzyme. You are investigating the deactivation of the enzyme at high temperatures. The deactivation rate constant kd follows the Arrhenius Equation. If the activation energy is 50731 J/mol and the pre-exponential factor Ad is 2.2x107 per h, what is the half-life (in hours) of the enzyme at 50 °C? = (R 8.314 J/mol/K)

Describe  at least five (5) unit operations that are used extensively in the separation processes  of  petroleum refining.

Make a McCabe-Thiele diagram and use it to distil a binary feed.

Which of the following statement is false for recycling of the polymers? A Polymerdegradation is the reduction in the physical properties of a polymer, such as strength.caused by changes in its chemicalcomposition. Degradation of polymerscan be done by using of thermal, chemical, biological and mechanical methods. In recycling process, poly merdegradation can occuras chain scission, branching, ox idation, grafting and crosslinking reactions. All polymerscan be recycleable.
