    hey normal to plane is 2i+1j+2k and it’s magnitude will be 3 so dividing normal by magnitude it gives 2/3i+1/3j+2/3k

  8. From the unknown In the following questions two statements are given one of the statement is labelled as ASSERTION and the ohter is REASON. Read the statement carefully and mark correct choice according to the following key: (a) If both ASSERTION and REASON are correct and REASON is the correct explanation of ASSERTION (b) If both ASSERTION and REASON are correct and REASON is the correct explanation of ASSERTION (c) If ASEERTION is correct and REASON is wrong (d) If ASSERTION is wrong and REASON is correct ASSERTION : The order of a reaction is related to molecularity. REASON : Molecularity of the reaction cannot be fractional.

    bt dude in assertion reasoningtype ques the statemaents shld be 100% correct with no exception.tht’s why ass. shld be incorrect bcoz in all cases order is nt related to molecularity

  9. From the unknown The rate of a reaction depends upon the temperature and quatitatively expressed in the form of Arrhenius equation, k = A.e ^ {\frac {E_a}{RT}}. The exponential term represents the fraction of molecules having energy to reach the transition state or cross the energy barrier. Pre-exponential factor gives the number of collisions per unit time. The data of two reactions is given below: (i) For the first reaction it is observed that 3.6 x 10 ^ {- 16} % reactant molecues exist in the activated state of a reaction at 300 K. (ii) At 25 ^ o C, the E_a of the second reaction, NO(g) + Cl_2(g) \rightarrow NOCl(g) + Cl(g) is 8.5 x 10 ^ 4 J mol ^ {- 1}. The fraction of collisions with sufficient energy is 1.2 x 10 ^ {- 15}. The activation energy of the first reaction is
