a) By direct substitution determine which of the following functions satisfy the wave equation. 1. g(x, t) = Acos(kx − t) where A, k, are positive constants. 2. h(x, t) = Ae where A, k, are positive constants. 3. p(x, t) = Asinh(kx − t) where A, k, are positive constants. 4. q(x, t) = Ae where A, a, are positive constants. 5. An arbitrary function: f(x, t) = f(kx−t) where k and are positive constants. (Hint: Be careful with...
The equilibrium constant for the following reaction
can be expressed by the empirical formula
in the interval 445 K < T < 460 K. Use this expression to
calculate ∆rH◦ and ∆rS ◦ at 450 K and derive
an equation for ∆fH◦ of Ag2O (s) in this
temperature range. Now use the following heat capacity data:
to calculate ∆rH◦ , ∆rS◦ , and
∆rG◦ at 298 K. Would Ag2O be automatically
decomposed when exposed to the atmosphere (the partial pressure...
