Let vec a_r=x_r hat i+y_r hat j+z_r hat k ,r=1,2,3 be three mutually perpendicular unit vectors, then the value of |[x_1,x_2,x_3],[y_1,y_2,y_3],[z_1,z_2,z_3]| is equal to 0 b. +-1 c. +-2 d. none of these

For reversible reaction : X_((g))+3Y_((g))hArr 2Z_((g)), DeltaH=-"40 kJ" Standard entropies of X, Y and Z are 60, 40and "50 J K"^(-1)",ol"^(-1) respectively. The temperature at which the above reaction is in equilibrium is

'X DeltaY' means 'X' is neither greater than nor equal to Y. 'X sum Y means 'X is not smaller than Y. 'X@Y ' means 'X is not greater than Y'. 'X © Y' means 'X is neither greater than nor smaller than Y' 'X #Y' means 'X is neither smaller than nor equal to Y. Now in each of the following questions assuming the given statements to be true, find which of the two Conclusions I and II given below them is/are definitely true? Statements : J(c) R, P sum R, Z#P Conclusions: I. R DeltaZ II. J@P
