Which reaction would cause a decrease in entropy? O A. 2NOCI(9) + 2NO(g) + Cl2(9)
OB. CO(g) + 3H2(g) → CH4(9) + H2O(9)
O C. 2NH3(g) → N2(g) + 3H2(9)
O D. 2CCI_(g) + O2(g) → 2CoCl2(g) + 2Cl2(9)

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products
