ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi and the reaction rate

using a pen and paper. Thanks to advancements in technology‚ there are modernized ways to gather‚ store‚ and transmit information more efficiently. The paper charting method has been shifted to a rather digital version of documentation known as the Electronic Health Record (EHR). The EHR provides a real-time and secure way to manage patient medical records. “Included in this information are patient demographics‚ progress notes‚ problems‚ medications‚ vital signs‚ past medical history‚ immunizations‚

The Effectiveness of Acceptances Communicated by Electronic Means‚ or — Does the Postal Acceptance Rule Apply to Email? Eliza Mik* The ‘traditional’ classification into ‘instantaneous’ and ‘non-instantaneous’ methods of communication must be abandoned. As all Internet transmissions are instantaneous‚ the choice between the principle of receipt and the postal exception must be based on other criteria. The focus must be shifted from communication devices to the characteristics of the communication

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Electronic Medical Records In this article the author explains patients’ records at healthcare facilities may now be stored using electronic medical records (EMR) instead of the paper charts that have been used in the past. EMRs have several disadvantages and advantages. One of the biggest disadvantages to EMRs is the high initial start-up cost. The healthcare facilities have to buy the equipment to begin the process. They also have to hire people to convert their current files from paper copies
