- 10(a). Hydrogen, H_(2) reacts with nitrogen monoxide. NO as shown below: 2H_(2)(g)+2NO(g)arrow N_(2)(g)+2H_(2)O(g) The rate equation for this reaction is: rate=k[H_(2)(g)][NO(g)]^2 The concentration of NO(g) is changed and a rate-concentration graph is plotted. 9.0 8.0 7.0 6.0 5.0 4.0 3.0 2.0 1.0 0.0 __ 7.0 0.0 2.0 2.0 30 4.05.06.07 3.0 4.0 5.0 6.0 The chemist uses H_(2)(g) of concentration 2.0times 10^-2moldm^-3 Using values from the graph, calculate the rate constant, k, for this reaction. Give your answer to two significant figures and in standard form. Show your working.
