Suppose you carried out the catalyst trial. Could you calculate, from your data, the value of Ea
for the reaction catalyzed by copper? If not, what additional experimental data would you
require in order to be able to do this? Would the value of Ea be greater or less than that
obtained for the uncatalyzed reaction? Explain. Please type your answers.

Expert Solution

The energy of activation for a catalysed reaction can be calculated if the activation energy of the uncatalysed reaction is known. The values of the rate constants for both the catalysed and uncatalysed reaction are calculated experimentally. The following derivation gives the final formula for the calculation of activation energy.

The catalyst increases the rate of reaction by providing a different path to the reaction. This means that it lowers the energy barrier i.e activation energy of the reaction of the reaction to give the product at a faster rate.

SO, THE VALUE OF ACTIVATION ENERGY OBTAINED FOR A CATALYSED REACTION WILL BE LOWER THAN THAT OF AN UNCATALYSED REACTION.

A reduction in net taxation, , could be carried out diﬀerent ways, for example, increasing the Earned Income Tax Credit, a transfer to lower-income workers, or decreasing the marginal tax rate for higher-income households. Do you think the form of the reduction matters for its eﬀect on equilibrium GDP?

Suppose that you carried out a Bacterial transformation of E. coli HA101 with pGLO plasmid experiment in the lab. During the experiment, plates with bacteria were inoculated from +GLO and -GLO microfuge tubes (LB (-) plate, LB/amp (-) plate, LB/amp (+) plate, and LB/amp/ara (+) plate). 5) What does LB (-) plate contain? 6) What does LB/ amp (-) plate contain? 7) What does LB/amp (+) plate contain? 8) What does LB/amp/ara (+) plate contain?

In this question you are going to calculate the data that could be used to construct a titration curve (pH versus volume of titrant added) for the titration of an aqueous ammonia (NH3; weak base, pKB = 4.7) cleaning solution with a strong acid (HCl). When strong acid is added to an aqueous solution, it immediately reacts and yields H3O + ions; thus the titration is described by the reaction: NH3(aq) + H3O + (aq)  NH4 + + H2O(l)...

Consider a private value auction with 2 bidders. The auction is carried out as a second price sealed bid auction where in case of a tie between the bidders, the winner is selected by a coin toss. The seller has valuation of the good of zero and will accept any bid at or greater than zero. Each bidder knows his/her own valuation, v, and does not know the valuation of the other bidder. It is common knowledge that the bidder...

Calculate the expected value with the information given. 1). You are trying to figure out if you can make money off of a new, and, maybe, poorly constructed, dice rolling game. Each time you play you must wager exactly $1. If you roll a 1-4 on a ten sided die, you will then roll an 8 sided die and receive 10¢ times the number rolled. If you roll a 5-8 on the ten sided die, you will receive nothing. Finally,...

The synthesis of methanol from carbon monoxide and hydrogen is carried out in a continuous vapor phase reactor at 5.00 atm absolute. The feed contains CO and H2 in stoichiometric proportion and enters the reactor at 25 oC and 5 atm at a rate of 17.1 m3/h. The product stream emerges from the reactor at 127 oC. The rate of heat transfer from the reactor is 17.05 kW. Calculate the fractional conversion achieved and the volumetric flow rate (m3/h) of...
