If a thermodynamical system is adiabatically isolated and experiences a change in volume under an externally applied constant pressure, then the thermodynamical potential minimized at equilibrium is the

Two parallel first-order liquid phase reactions \( A \xrightarrow{k_1} B \) and \( A \xrightarrow{k_2} C \) are carried out in a well-mixed isothermal batch reactor. The initial concentration of A in the reactor is \( 1 \) kmol m\(^{-3}\), while that of B and C is zero. After 2 hours, the concentration of A reduces to half its initial value, and the concentration of B is twice that of C. The rate constants \( k_1 \) and \( k_2 \), in h\(^{-1}\), are, respectively,

Let \( p(\bar{p}, \bar{q}, t) \) be the phase space density of an ensemble of a system. The Hamiltonian of the system is \( H(p, q) \). If \( \{A, B\} \) denotes the Poisson bracket of \( A \) and \( B \), then \( \frac{dp}{dt} = 0 \) implies

Consider a Keynesian Cross Model with following features,
Consumption Function: C = C0 + b(Y-T) 
Tax Function: T = T0 + tY 
Income Identity: Y = C + I0 + G0

G = Government Expenditure; b = Parameter; t = Tax Rate 
(The subscript 0 (zero) indicates that the concerned variable is autonomous) 
If b = 0.7 and t = 0.2, value of the Keynesian multiplier is ________ (round off to 2 decimal places).
