(a)    H2 and O2 do not react at room temperature because required activation energy is not available despite having negative \Delta G.

(b)    \mathrm{A}_{2}+3 \mathrm{B}_{2} \longrightarrow 2 \mathrm{C}

        order = 0 

        Rate equation = R = k [A]^0[B]^0

                                       R = k
