For the reaction at equilibrium: `A(g)+2B(g)hArrC(g)` Equilibrium constants as function of temperature are K at `300^(@)C 4xx10^(-4)` K at `450^(@)C 4
Only decreasing temperature, `k_(eq)` increasing so reaction is exotehrmic in forward direction

In an economy investment increased by 1,100 and as a result of it income increased by 5,500. Had the MPS been 25 percent, what would have been the inc
`DeltaY = DeltaI = (1)/(MPS)` `5,500 = (1,100)/(MPS)` `MPS = (1,100)/(5,500) = 0.20` `Delta Y = (1,100)/(0.25) = 4,400`

Two processes, which are taking place in opposite directions are in equilibrium. How to write equilibrium constant
(i) Equilibrium in a system having more than one phase is called heterogeneous equilibrium. If ethanol is placed in a conical flask, liquidvapour equilibrium is established. C2H5OH(l) ⇌ C2H5OH(g) For a given...

equilibrium constant is The value of \( K_{ p } \) for the equilibrium \( NH _{4} H S_{(s)} \rightleftharpoons NH _{3(g)}+ H _{2} S _{(g)} \) at a certain temperature and total 2 atm pressure at equilibrium will be \( atm ^{2} \)
We have given, Total pressure at equilibrium = 2 atm. Constant temperature = NH4HS(s) \(\rightleftharpoons\)NH3(g) + H2S(g) Kp = \(\frac{P_{NH_3}\times P_{H_2S}}{P_{NH_4HS}}\) ∵ Partial pressure of solid substance is considered to be 1. ∴ Kp = \(P_{NH_3}\times P_{H_2S}\) Kp = \((P_{NH_3})^2\) (From the...

Explain why specific heat capacity of a gas at constant pressure is greater than that at constant volume.
1. When the gas is heated at constant volume. there is no work done against external pressure. 2. Hence, all the supplied heat is used in raising the temperature of the...
