Yes, the reaction is spontaneous.

Explanation:

We can answer this question by examining the standard reduction potentials for the half-reactions.

$m m m m m m m m m m m m m m m m m m m m m m m m m m m m l E^{\circ} /V$ $color(white)(mmmmmmmmmmmmmmmmmmmmmmmmmmmml) E^@"/V"$
$2 \times [{MnO}_{4}^{-} + 8 H^{+} + 5 e^{-} \to {Mn}^{2+} + 4 H_{2} O]; m m m m m m l +1.51$ $2×["MnO"_4^"-" + 8"H"^"+" + 5"e"^"-" → "Mn"^"2+" + 4"H"_2"O"]; color(white)(mmmmmml)"+1.51"$
$5 \times [H_{2} C_{2} O_{4} \to {2CO}_{2} + {2H}^{+} + {2e}^{-}]; m m m m m m m m m l l +0.49$ $5×["H"_2"C"_2"O"_4 → "2CO"_2 + "2H"^"+" + "2e"^"-"]; color(white)(mmmmmmmmmll)"+0.49"$
$2 {MnO}_{4}^{-} + 5 H_{2} C_{2} O_{4} + {6H}^{+} \to 2 {Mn}^{2+} + 10 {CO}_{2} + 8 H_{2} O; +2.00$ $2"MnO"_4^"-" + 5"H"_2"C"_2"O"_4 +"6H"^"+" → 2"Mn"^"2+" + 10"CO"_2 +8"H"_2"O"; "+2.00"$

The condition for spontaneity is that $ΔG < 0$ .

$ΔG^@ = -nFE^@$

Since $E^@ > 0, ΔG^@ < 0$ , and the reaction is spontaneous.
