If the length and breadth of a rectangle are doubled then its perimeter is (1) tripled (2) doubled (3) made half (4) None of these
(2) Let the initial length and breadth be l and b, respectively. So, the initial perimeter = 2 (l + b) The final perimeter = 2 (2l + 2b) =...

20 mol of Chlorine gas occupies a volume of 800 mL at 300 K and 5 x 106 Pa pressure. Calculate the compressibility factor of the gas.
P = 5 x 106 Pa = 5 x 106 / 105 bar n = 20 T = 300 K R = 0.083 L bar K-1 mol-1 Vreal = 800 mL Videal = nRT/P Putting values ,...

Calculate ∆G and ∆G0 for the reaction : A + B ---> C + D At 27^0 C. Equilibrium constant (K) for this reaction =10^2
∆G =0 because the reaction is in equilibrium. ∆G0 =- 2.303RT log K = - 2.303X8.314JK-1 mol-1 x300K log 102 = -11488J mol-1 = -11.488kJmol-1 .

The equilibrium constant of a reaction at 27^o c is 1.6 and at 127^o c is 7.6 respectively. Is the reaction exothermic or endothermic?
As the value of equilibrium constant increases with increase in temperature so, the reaction is endothermic in nature.

A flask is of capacity of one litre. What volume of air will escape from the flask If it is heated from 27^oc to 37^oc? Assume pressure constant.
V1=1litre V2=? T1= 270c=300k, T2=370C=310k At Constant pressure, V1T1 = V1/T1=V2/T2 1/300=V2/310 V2 = 1.0333 litre Since capacity of flask is one litre Volume of air escaped out = 1.0333-1= 0.0333 litre = 33.3ml

In a reaction if the concentration of reactant A is tripled, the rate of reaction becomes twenty seven times.
Three, because rate = k [A]3
