There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: k=Ae−Ea/RT where k is the rate constant, A is the frequency factor, Ea is the activation energy, R=8.314 J/(mol⋅K) is the universal gas constant, and T is the absolute temperature. __________________________________________________ A certain...

Consider a simple series RLC circuit with the following values for the resistance, inductance, and capacitance: R = 110 Ω (ohms), L = 1 H (henries), and C = 0.001 F (farads). Furthermore, a battery provides an external voltage, e(t), into the circuit equal to 7 However, this external voltage e(t) is not always flowing into the circuit. Initially, the switch for the circuit is open and there is no charge or current flowing through the circuit. At time t...
